Neutral Definition and 338 Threads

Under normal circumstances both plates of a parallel plate capacitor develop a charge imbalance in each plate as the capacitor gets charged, the charges redistribute with one plate lacking electrons and the other plate having an excess of electrons, both plates together still can be though of as...

I'm talking about a situation like this. Ive been told that charge distribution on the inner side of the conducting material is non uniform and equal to -q. This makes perfect sense But ive also been told that the charge distribution on the outer part of the conducting material is ##uniform##...

Let me start this off with saying I am just a uneducated idiot, But after reading about Zap Energies sheared flow pinch reactor I was wondering if you could use a similar concept in a neutral beam injector? Like could you first compress and heat the plasma inside of a NBI using a pinch, then...

Let's think now about the energy to create a KF molecule from neutral atoms. First we need to ionize both K and F: K loses an electron and F gains an electron. Then we have to bring the ions together. The first ionization energy of K is 418 kJ/mol and for F is 1681 kJ/mol. The electron...

Also referring to the post by @Kostik plus answers, I'm wondering about surface charges of neutral solids such as metals or carbon, for example. I only want to discuss large scale effects so that the solid can be treated as continuous. The atomic structure is averaged out. I also assume that...

For (a) this problem, the only thing I can see changing is the distribution of the negative charge on the inner wall of the cavity. When the point charge is in the center of the cavity, you could say the induced charged is spread symmetrically on the inner cavity wall in order to oppose the...

Hello! I see that in experiments at facilities like ISOLDE, they produce molecular beams at energies of tens of keV. If I understand it right, they first create the molecule as a positive ion, and using electric fields (and maybe magnetic for mass selection) they take the particle out of the...

Moderator’s note: discussion spun off from https://www.physicsforums.com/threads/the-nuclear-power-thread.9091/page-43#post-6558385 Sometimes I don't understand the Germans, so technically advanced and forward thinking and yet somehow willing to abandon logic on this one. Their alternative is...

The answer key states the the answer is D but the explanation makes no sense to me. “ amphoteric means that it could behave either as an acid or as a base. The alcohol group is not the key in aqueous solution. Terminal Alkynes are acidic”. I don’t see a terminal triple bond.

Hi, I have a question, I think the answer is no you can't do it, but I want to know why. First mains supply - 3phase N + E (50hz) Connected to this first supply is an inverter that gives out a 3 phase 415vac @60hz (no neutral) second supply. The 60hz inverter output feeds 3 independent tapped...

Flat rotation curve in galaxies is determined by observing neutral hydrogen which is co-distributed with dark matter. What is the rotation curve profile of neutral hydrogen in galaxies where there is less dark matter?

A transformer supplies 240VAC to a 20A circuit breaker as shown in the attached image. I believe I can use 12AWG wire for wires X1, X4, 2 & 3. However, I'm not sure what gauge wire the neutral should be. Maybe 12AWG or something larger?

Last weekend I was in my friend house to change an outlet from 127V to 220V. This means changing the neutral terminal from the bar inside the electrical board (dont know if that's the right rem in english) into a phase. However, I couldn't identify which neutral cable was from the circuit I...

I think i read somewhere that jet engine shaft is neutral,because forces at turbine and compressor cancle out,so that mean axial berings don't have force on it in direction of thrust!? (this can't be true,becsue in that case thrust will be zero...) But if this is true ,against what pressure...

Details to follow if there is interest.

In decay processes where no mixing between quark families is present, the mediator of the weak force is the neutral ##Z^0## boson. If that is the case, how is it experimentally possible to detect neutral currents in processes such as: $$\bar{\nu}_\mu + e \rightarrow \bar{\nu}_\mu + e$$ What...

I started combining 2 pions: ##|\pi ^{0},\pi ^{0} >=\sqrt{\frac{2}{3}}|2,0>-\sqrt{\frac{1}{3}}|0,0>## What should i do now? Should i continue combining the third pion or can i already say that it's forbidden? If yes, why? Is it because the state antisymmetric, impossible for two bosons?

Here's how I approached it. We know the total mass of the cloud, it is given. Let's call it 'M'. We can also find out the mass of a single hydrogen atom from its atomic weight. Let's call this 'm'. Then N = M / m is the total number of hydrogen atoms in the cloud. The temperature (T) is given...

Sir how can one explain with the help of an analogy to a grade 10th student the reason behind not getting a shock on touching the neutral wire of the household AC circuit, even though the current flows alternately through live as well as neutral wires.

If a solid (a few nm diameter) was placed in vacuum inside a grounded hollow sphere, but without touching the sphere (zero gravity), qualitatively what would the potential inside this solid be on average? In other words I don't want to look so closely that I see the potential wells of the...

Hi I've recently started learning about electrical three phase theory, and therefore got some questions. Imagine the following: Countries like Albania, Norway ++, have IT earthing configuration in their distribution grids, i.e. the neutral point is not solidly grounded, however "grounded"...

Trying to learn the game Go. I have a question in regards to the uploaded pic. Why is the empty spot neutral? Couldnt white just place a stone there and capture all of the black stones since all of blacks liberties would be taken?

Hi guys, Merry Christmas to you all! I wanted to know whether a neutral pion can be made up of a strange quark and an anti-strange quark. I know that the kaon is the only strange meson and all variations contain an s quark but wouldn't the strangeness be zero in an s quark/anti-s quark pair as...

In our practical world, the voltage between the neutral wire and the ground is not exactly 0V, and there's some small current passing through the wire connecting the neutral wire to the ground, how do you mathematically calculate this voltage drop?

At first I always imagine that there were 2 live wires connected to a source and a load, and one of them is connected to the ground via an additional wire, but apparently people said this is wrong, because it would just blow the fuse, as you are 'short circuit' - ing the connection. Is this true?

The left circuit is a simple live&neutral circuit, it is neutral (0V), because it is in fact 'grounded'. If I unplug the wire connection to the ground, makes both wire, live. Now, If I replace the grounding connection with a person, why would he receive the shock, doesn't the man 'neutralize'...

If I touch the neutral wire while the circuit is still connected, will I get the same electrical shock as if I touch the live wire?

if a random electron strikes a neutral conductor does it get absorbed and increase the voltage of the conductor

What's the difference between neutral and stable? As an example of H2. Here two H atoms combine and make an H2 molecule. Now two H atoms are neutral as they have the same number of protons and electrons. So the H2 molecule is neutral. on the other hand. Two H atoms combine through a covalent...

The nucleus of the H atom is neutral when it has two electrons and one proton (when forming a covalent bond) or it has one electron and one proton.

Are Cl2, O2 , H2 etc are nutral molecules? As we know their atoms are neutral such as Cl. It has 17 protons and 17 electrons. Because it has the equal number of protons and electrons, it is a natural element. But when two Cl atoms combine through covalent bond by sharing a pair of electrons...

I was vacuuming my house, the vacuum cleaner is 1600w rated I remember, then i unplugged the cord from wall socket and I observed something interesting , and to be honest I remember I have seen this before with my washing machine and elsewhere, when I take out the plug from the wall socket I...

So I've been learning how batteries work. What I learned is that a battery consists of 2 pieces of metal both with different electronegativities. These metals react with an electrolyte. One metal (called the anode) is oxidized and has its electrons removed, leaving behind a positive ion which...

I found an old paper online (1962) I think, stating that bremmstahlung occurs between different neutral atoms in collisions. Am I correct in assuming that this will result in frequencies outside of the usual line broadening mechanisms? Thanks

Hello! I wanted to ask why does the neutral Σ decay almost always to one γ(or two) and a neutral Λ. Why can't it decay to anything else? Thanks!

My brother had something (squirrel?) break the neutral wire from the pole to the house a while back. He said all the lights dimmed, some of the appliances started to hum loud and it blew a couple breakers. After resetting the breakers and poking around a bit he eventually took a reading, found...

I had learned from a book in a lower class that electric power distribution from the generating station is done in phases. Like in India, we have three phases of power transmission: the red, green and yellow colours distinguish the three phases. I believe the same is the case in any other...

Hello, In three-phase systems, star coupling for example, and in the case where single-phase sources are supplied using the three phases L1, L2 and L3 with a common neutral return, My first question is: when one is balanced il1 = il2 = Il3 is what the current flowing in the neutral is...

<Moderator's note: thread split off from https://www.physicsforums.com/threads/lhc-absence-of-supersymmetric-particles.917829/> I wonder how unexpected, or not, was the discovery of neutral currents.

I'm going to pick on Germany a bit here, based on something I recently learned in the solar power thread: About 9% of Germany's power is produced by wood biomass burning, second only to wind in their "renewable" sector. Clearly, wood can be "renewable", but to me the more important question is...
