AI Thread Summary
Electricity is fundamentally the interaction of charged particles, primarily electrons, which are free to move in conductive materials. When an electric fan is plugged in, it completes a circuit, allowing alternating current (AC) to flow, which is characterized by electrons moving back and forth rather than in one direction. The flow of current generates a magnetic field that interacts with the motor's components to produce motion. The concept of voltage serves as the driving force for this flow, akin to pressure in a water pipe, where the number of electrons passing a point per second defines the current. Overall, electricity encompasses various phenomena resulting from these interactions, making it a complex yet essential aspect of modern technology.

So I have these huge doubts on the deep nature of the force we refer to as "electricity" or "electric current" in our daily lives.

I want to know exactly what it is and most online resources are very circular (electricity is electric current which is electric fields which is electricity etc.)


It's difficult to know what to ask first but let's devise a simple practical example for starters.

When I plug my, say, electric fan to the outlet and turn it on, is it a bunch of free electrons that pour into its electric motor and power it? I think it's not, but then what is it? Is it an excitation of electrons that passes on as a wave (more like it)?

Well I have many more questions but they'll only pop out when the dialogue is started! Thank you!

Welcome to the PF. That's a very broad question. Perhaps it would be better if you read through this article:

http://en.wikipedia.org/wiki/Electric_current

and told us specifically what you find confusing. Thanks.
 
Electricity is a very broad topic. However, the fundamental thing to remember is that it is an electro-magnetic wave - i.e. it travels quickly. Energy is transferred from point a to point b by this electro-magnetic wave. For electricity to travel there must be a ring or circuit. This is because the electricity produced by moving magnets follows a circular path. Voltage and current are a very convient means to analyze circuits but break down on even simple things like a plug - i.e how does current jump from the socket to the plug.

Kind regards,

Cyclops
 
Well at its core 'electricity' reflects the fact that atoms are made of charged particles, the important one for electricity being electrons. Now in substance that are metallic these electrons are not really associated with anyone atom and have a certain freedom. In addition every charged particle emits an electromagnetic force of the form \frac{kq_1q_2}{r^2} on other charges. From these simple facts (more or lesss) we get the richness of electricity.
 
In terms of electric current, when you plug in your fan into the wall the circuit is completed, meaning that there is a flow of electrons through the circuit. In the case of a household it is AC (alternating current) meaning that the electrons go backwards and forwards real fast instead of flowing in one direction.

The flow of current is associated with magnetic fields. When there is a current flowing through a wire, there is a magnetic field expanding in concentric circles around the wire. This magnetic field is utilised in an electrical motor to provide a force.

An electric motor is composed of a coil of current carrying wire in a magnetic field (two magnets on either side of the coil). When electricity is running the magnetic field of the wire interacts with the magnetic field of the magnets and causes the motor to spin. This motor is what is used to spin the fan.

Any of this can be expanded on so feel free to ask questions :)

The word electricity is a general name for the whole process, as when we say that an appliance uses electricity.

Current is a specific measurement, the rate at which electric charge flows, so if 100 coulombs of charge were to flow past any given point in 25 seconds, the current would be 4 coulombs per second, which is called 4 amperes.

It's true that metal wires have a lot of free electrons, but then they have to be caused to move. When you plug it in, the voltage produces a directionality that is similar to the sense of up and down in a gravity problem. As gravity makes it the spontaneous direction for a ball to roll downhill, the applied voltage makes it become the spontaneous direction for the electrons to move in a certain direction.

Rightfully electricity is nothing more than the ways through which we can observe it, e.g. generating light, driving engines, heating and so on. The theory of electromagnetism is just a framework that exists in our heads to help us make sense out of these different phenomena. Therefore one should be careful to say that a different phenomena for sure are manifestations of something fundamental called electricity (although the evidence supporting the claim is overwhelming :smile:).

Let's say electricity is the knowledge of how charges interact. But since we know of many different particles carrying charge, isn't electricity then just a property of matter rather than something real in itself?

My point is: the what is question can never be given an indisputable answer because it's so dependent on our current knowledge and our somewhat arbitrary way of expressing physical laws.

It's good to have such doubts/questions..that's sometimes how progress is made when someone realizes current understanding is limited/incomplete/superficial or whatever.

In the the case of electricity, it is quite amazing! While free electrons are involved it's more than just that: Power is volts times amps, P =IE, so making EITHER current or voltage higher, or both, produces more power. If either is zero, then no power! And it DOES take a LOT of electrons: from q = it, you can figure how many electrons (one coloumb) flows for one amp for one second: about 1018 !

Electric power is a means of converting either mechanical energy (alternator or generator) or chemical energy ( a battery) into a convenient form for wide application.

Thank you all for the replies! I've been having time constraints to reply.

But one main question is in my mind: if free electrons are jumping from atom to atom, then at some point some atoms will start running out of electrons? If the elements' chemical properties are defined by the amount of electrons (among other things), they if they lose electrons they will become freaks?;)

A good question but unfortunately I can't think of a good way to answer it in an explanitory way... How good is your math (calc/DE's is all you really need to tackle this one)?

the atoms don't actually lose electrons. in the metallic bonding model the metallic atoms bond by rejecting their valence electrons. This results in a veritable sea of electrons that is free to move through out the metal structure. Incidentally this is the main reason for many of metallic objects properties such as being good conductors of heat and electricity and lustrous look.

When an electrical current is flowing through a metal the electrons are getting moved around the circuit. In terms of plugging in your fan, just as many electrons come out the plug as go into the plug. This means that the overall amount of electrons stays constant within the circuit.

there has always been an analogy of electricity being like water in a pipe. Electrical current is like water flowing through a pipe. The same amount of water will come in the pipe as goes out the pipe. the amount of water passing a pipe at any moment is the rate of flow. in electricity the number of electrons passing a point every second is measured in amps. One amp is coulomb of elevtrons per second. A coulomb itself is a set number of electrons, akin to how eggs often come by the dozen. The number of electrons in one coulomb is 6.25 x 1018.

The voltage is sometimes explained as the pressure of the water in the pipe. The voltage, which is also called the potential difference is what essential the driving force behind the electric flow. Just as a mass has a gravitational potential when raised up in the air, the voltage is the electrical potential in a circuit. One of the best definitions of voltage I've come across is:

If it takes 1 joule of energy to move 1 coulomb of electrons through a circuit, then the voltage of the circuit is 1 volt.

this means if you move 1 coulomb half way around the circuit 1/2 a volt has been used.

hope this helps :)

Well there's no "analogy" the equations of classical EM WERE the equations of fluid dynamics. However, this isn't actually the correct picture. What you're presenting here is essentially the drude model which does not correctly predict a great many things in condensed matter (like thermoconductivity)

OK the water through pipe model is quite helpful. But I would like to illustrate the matter a little further.

For instance, our classic copper wide. Its made of copper atoms, plus impurities which can be ignored for the moment.

A copper atom contains 29 electrons, distributed in four layers 2, 8, 18, 1.

So we have Cu(2,8,18,1) or Cu(29) to represent a copper atom in plain text. If the nucleus is considered, it contains 64 neutrons and 34 protons (correct me if I am wrong).

So we would have gazillons of atoms of copper bound to each other:

29P+64N+29E = atom of copper x gazillions.This mass of 29P+64N+29E would then, according to the properties of free electrons found in transition metals (why is that?) be constantly losing and gaining one or more electrons from their Copper neighbors, but each atom would always maintain 29 eletrons around their nuclei, right?

Then what exactly is being produced at my local powerplant and what is my computer "gaining" that powers it? Its not being fed with excess electrons, that I know. It's being fed with "electric charge", which is made of nothing, apparently!

Apparently, after a 20 minute pause from last paragraph, I can only assume what being fed to my computer is, basically, "INFORMATION". The electrons of my lithium-ion batteries are being reprogrammed to contain an unstable amount of "charge" which does not occur without the rotor at the local hydroplant convincing my copper atoms in its motor somehow that their charge changes... wait I am onto something I am having an insight here but I lack more concepts, I lack more knowledge. Please analyse the babble in this paragraph and provide some info on what this "charge information" is...

Only valence electrons contribute to the "fermi sea". The why? Well I'd direct you to band theory.

No no, I mean we can better frame, I suppose, IMHO, the problem of picturing electricity if we think of it as information. I know its not easy, but electricty is not like water, there is no actual current. Water is H2O being moved from place to place. Electricty is not electrons or any particles being moved around, no!

It's just the properties (=information) they possesses which is being manipulated. Am I wrong in this approach?

  • #25
I think that's misleading, mopc. The word "information" implies some pattern that has numerous combinations, like a code with many possible values, many words in a language, etc. But electricity is about relatively high or low potential energies. You have a device doing work to put charges at a point in space of higher electrical potential energy, and then those charges return to a lower electrical potential energy. I don't see a comparison to "information." You could, of course, encode information with electrical devices that are variously on and off, but you could also encode information with a pattern of colored jellybeans or anything else that has identifiable states. That doesn't mean that electricity is information.

But there ARE charges being moved, mopc. In the case of current in metal wire those charges are electrons. In the case of a solution of an ionic compound, say you dissolve salt in water, this can conduct current with positive ions going one way and negative ions going the opposite way, so you would have two kinds of current carriers with charges of opposite sign. For a current in a metal wire, you have one type of carrier, electrons. The electrons travel through the crystal lattice that is the atomic structure of a metal.

And what are "charges"? Just a property of the electrons, some kind of inherent information they just possesses and is made of nothing. Right?

Have a look at a the workings of a vacuum tube. Take for a start the diode. It's absolutely true that electrons fly from the cathode to the anode. This can be shown by the impact electrons have on the bombarded anode.
Or similar: in a triode the flow of electrons is slowed down or stopped altogether by placing a grid in between.
In the connecting wires there must therefore exist a flow of electrons analogous to water flow.
Of course all other comparisons with water must stop here.

mopc said:

When referring to the movement of charges it means the movement of electrons. I'm actually not certain what a charge itself actually is. It is quite an obscure little thing. A proton has a positive charge and an electron has a negative charge. Similaraly the neutral neutron can be split into an electron and a proton (beta decay).

mopc said:

In this concept charge is not very useful. Charge on its own has little meaning.
Similar the unit Volt on its own has little meaning.

Useful to know is : how many electrons have flowed through a potential difference of x Volts. Then: unit charge e times applied voltage difference is the potential energy per electron.

Therefore I would not be surprised when sometime in the future these concepts for electrical currents are left behind and we just speak of energy per electron or electrovolt.

Yes but the electrons never actually leave the copper wire's atoms! Othewise we'd end up with a bunch of electronless atoms. What then "feeds" an electric device? Charge?
 
  • #34
So here's what I think electrical power is.

An copper wire, for instance, has normally a bunch of atoms with mutually cancelling opposing charges:

++--+++--+-++---+++--+---+++--+-+++--+++--+-++---+++--+---+++--+-+++--+++--+-++---+++--+---+++--+-+++--+++--+-++---+++--+---+++--+-+

If you just insert the wire into an electric motor, sure nothing will happen, because the metal in the motor is virtually neutrall too. No compensation has to occur.

Now when you plug the wire into a generator, the generator has a way to make its own atoms "unbalanced" (say, much more negative than positive = ---+--------++------+--------++----)

Therefore the properties of the wire's copper atoms start acquiring that unbalance in an attemp to compensate for the contact with an unbalanced neighbor. That start moving the charges around. The electric motor of my refrigerator, when plugged into that generator + wire complex, also feels the urge to dance around with it, exchanging charges to compensate for the unbalanced, overly negative charge of the wire+generator system.

Since the electric motor has a metal wheel and a magnet, when that metal wheel tries to compensate, it spins because the atoms of the wheel are being affected by the magnet in it.

Ok that sounds wrong, but how would you correct my explanation?
 
  • #35
mopc said:

Look at this pattern. Mass and charge are properties of matter. All matter possesses mass, some matter possesses charge. Mass is positive; charge is either positive or negative. Mass attracts, and is attracted by, other masses, due to gravitational force; charge attracts, and is attracted by -- or repels, and is repelled by -- other charges, due to electric force.

If such properties are what you mean by possessing information, okay, but I think it's not society's standard use of such a phrase.

As for whether effects that obviously exist are "made of nothing", that sounds to me like a branch of philosophy, not an outlook that will help someone solve problems, explain processes, predict results, which is science's job.

mopc said:

Never is a very short time, and not quite right.
In a short time called "relaxation time" there's a slight imbalance in which one
electron will have flowed a certain distance before being replaced by the one behind.

mopc said:
Ok that sounds wrong, but how would you correct my explanation?

mopc, if you delve now into the subject of how motors and generators work, that's like skipping a hundred pages in the textbook before your real solid about the previous chapter.

The kind of questions you are asking indicate that you're not completely familiar with the concepts of potential energy, and this is where an analogy with gravity is helpful.

In a gravitational field, if you lift a mass to a higher altitude, say, you carry a rock to the top of a mountain, you're giving it potential energy, because when you release it then it will fall back down. You did work to displace it in the non-spontaneous direction, upward, and when it's released it will respond to a field that exists in its vicinity of space, gravity, by accelerating in its spontaneous direction, downward.

Electricity is very similar, but now it's an electric field instead of a gravitational field. If you move a positive charge closer to the positive terminal, or move a negative charge closer to the negative terminal, you're doing work on it to compel it to go in the direction that it's naturally repelled from. This gives it potential energy. Then you will observe that it moves spontaneously the other way, a positive charge moving toward the negative terminal, or a negative charge moving toward the positive terminal.

A battery has a chemical reaction that continuously puts out electrons in one place and takes in electrons in another place, causing regions of space that have relatively higher and lower potentials to be maintained. What a battery is doing is like a person doing work to carry a bunch of rocks up to the top of a mountain, and allowing them to roll back down, continuously putting things in a location where they will acquire potential energy, the tendency to start moving spontaneously in the opposite way.

You also asked about the meaning of the word "power". To continue the analogy with gravity:

To get to the units of energy per unit time, which we call power, simple reasoning will tell you that you will have two variables to multiply. One variable is current, and that's analogous to how many buckets of rocks you have to carry in a given amount of time. The other variable is voltage, which is like the fact that you're carrying those buckets of rocks up a steep slope instead of carrying them on level ground. You will have to multiply these two things. Therefore, power means current multiplied by voltage.

Numerical example with units: If 5 amperes of current flow, which means the movement of charged particles at rate of 5 coulombs per second, and if these charged particles are being displaced across a potential difference of 10 volts, then power is being delivered at a rate of 50 watts, which means electrical energy is supplied at a rate of 50 joules per second.

These are still not enough fundamentals to explain how motors and generators work, which requires a discussion of additional effects, the magnetic field and magnetic forces.

This paragraph is close to what I want to know. But what is a potential difference of 10 volts? Oh I researched, potential difference is merely another name for voltage. Voltage is like electric pressure. So apparently voltage is what happens when you have a difference between two lumps of matter with different electric charges. One electric charge will flow to where it is attrached, and vice-versa. Like my diagram full of +'s and -'s.

Voltage is the intensity of that flow. Right? Damn.
 
  • #39
Your question about what voltage (that is, potential difference) really means, answer: potential energy per unit of charge.

This would be the simplest derivation, algebra instead of calculus.

Equation 1: electrical potential energy is equal in magnitude to work W, which refers to a force F acting through a distance d: W=Fd

Equation 2: an electric field E acting on a charge q will cause it to experience a force F: F=qE

Substituting eq. 2 into eq. 1: W=qEd

So the product Ed is the work done per unit charge, and after you multiply that Ed by charge q you will have an expression for work or energy.

Define the potential difference V to be the term Ed, that is, the work per unit charge.

V=Ed
W=qV

To move a charge q across a potential difference of V, you will do work in the amount of (and change its potential energy in the amount of) W=qV.

When a charge of 3 coulombs is moved across a potential difference of 9 volts (that is, 9 joules per coulomb), the work done, and the change of its potential energy, is 27 joules.

But work done by what or by whom?

If the charge moves in the spontaneously attracted direction, say, negative charge approaching the positive pole, we would say the electric field performed 27 J of work on the charge.

If an active device, a supplied energy source, such as a battery, moves the charge in the non-spontaneous direction, negative charge approaching the negative pole, we would say the the energy source did the work on the charge, and did work against the electric field.

I'm an electrical engineer and there are sometimes minor difference in terminology between what I call things and what the physics community calls them.
