An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. In electric circuits the charge carriers are often electrons moving through a wire. In semiconductors they can be electrons or holes. In a electrolyte the charge carriers are ions, while in plasma, an ionized gas, they are ions and electrons.The SI unit of electric current is the ampere, or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.Electric currents create magnetic fields, which are used in motors, generators, inductors, and transformers. In ordinary conductors, they cause Joule heating, which creates light in incandescent light bulbs. Time-varying currents emit electromagnetic waves, which are used in telecommunications to broadcast information.
If you have 3 phase power and let's say
line A & B = 10 amperes
line B & C = 10 amperes
line C & A = 10 amperes
For the single line B. Since it's in both in the first and second lines, then B can experience 10 + 10 = 20 Amperes? Or is it 15 A or still 10 Ampere?
Thank you.

I'm trying to figure out how to calculate how much energy is stored in a battery between certain voltages. I know capacity is traditionally calculated by multiplying amps drawn by nominal voltage by time, but this seems like an approximation because voltage decreases as the battery is...

ok i want to make 1g/sec of hydrogen out of an unlimited supply of water, i know the electrolysis won't start below 1.48 volts, let suppose i am supplying 2 volts of DC current, i need to find out the total wattage for electrolysis, for this i need the amount of current required to produce 1...
The circuit breakers of my house say that they are 15a (the majority of them). The rms voltage is 120v for the outlets, and so the peak voltage is about 170v. I was wondering, if I hypthetically connected the terminals together with a 10 ohm resistor, would the breaker trip? I don't know if the...
Hello.
I have been running several experiments on an electrolytic cell, and I am trying to determine if side products are being formed at higher voltages. My thinking is that once the initial potential barrier is broken, and the resistance stabilizes, a volt vs amperage graph should be linear...
If current is always the same in a series circuit then how is a transformer able to make the current smaller when it increases the voltage? is this just an exception since with the voltage being higher the same amount of power is being provided?
I feel that I don't understand how voltage works in a circuit. I understand voltage to be electric potential energy per unit charge (kq/r). In the case of a circuit, electrons flow from low potential to high potential. But I don't understand how resistors cause a voltage drop. Isn't voltage...

Hello all,
I'm new to the forum, and hoping someone in here can help figure out the answer to my dilemma. I'm debating whether to build a new phase converter for a 3 phase welder, or reconfigure my current welder from 230VAC to 460VAC. I know the standard equation for watts is- Watts =...
I have a VFD fan that pushes air through a filter. Over time, downstream resistance gets higher due to the filter. Fan speed remains constant. We have looked at amperage draw and it has remained stable even with this added resistance. Does that mean that air flow remains constant?

Hey everyone, I wish to spark no heated debate, but is it possible, to have a flow of electriciy with a high voltage amount but at low amps? Or vice versa, low voltage but very high amps?

If I have 50 farads at 12 v, does this mean this power bank can discharge 600amps in 1 second based on 1 farad = 1 amp per second per volt ?

120 | 4
140 | 8
160 | 12
180 | 16

What are the advantages of having high amperage? By the way, I'm rather new to electronics.
I know that having high-voltage reduces the energy loss through the wire, and you don't need as thick a wire. But I cannot find the advantages of high amperage on the internet. This may be due to my...
Was wondering if I kept the wattage for say a 100 watt bulb constant but varied the voltage would the light be able to continue functioning normally?
Also, assuming this is true does this hold for more complicated circuitry?
Thanks.

My cars factory wire diagram is not that helpful - If a wire is feeding a terminal block that supplies 12v to a 20amp circuit (power windows) and the other is a 30amp circuit (A/C), and the possibility exists for both circuits to be drawing max amperage, shouldn't that main supply wire be able...
What happens if you take a high amperage supply from a transformer so that current was forced to flow a certain way in a conductor and you arc a high voltage supply over to this conductor also would you have high amperage and high voltage?

I don't understand how these tasers that have 50,000V only produce a very low amperage. According to Ohm's law that should kill you. Voltage divided by the persons resistance (Ohms).
