Neutral Definition and 338 Threads

I've never read this explicitly, but here is what I've concluded: If you could somehow have a perfectly balanced load on the circuits in your home to each of the 2 hot lines coming into your residence from the pole mounted transformer, this would mean: The neutral wire connected from your...

Would like to see if I've understood this question somewhat. :-) Homework Statement A doubly ionised Lithium atom (Li^++) has two of its normal complement of electrons removed. The energy levels of the remaining single electron ion are closely related to those of the neutral Hydrogen...

Hi, Once the Universe has completed reionization (at redshift >~6 ), the intergalactic medium (IGM) is completely ionized (even if some neutral clumps can persist). On the other hand, it seems that galaxies were accreting a lot of gas from the IGM after reionization so that they could form...

Hi Everyone, I'm a math grad student working on numerical procedures for the Dirac equation, and I'd like to be able to incorporate the neutral current interaction neutrino + fermion -> Z bozon -> neutrino + fermion <- poorly impersonated Feynman diagram into the Dirac equation as a...

Hey guys, as the title says I can understand why the neutral axis does not pass through the centroid after reaching a point where the bending moment is max before the beam collapses. Say you have a straight structure supported by two double I-Beams and a weight in the middle. Why does the...

Homework Statement A charge, Q2 = -7.00x10^-6 C, is 8.00 cm to the right of charge Q1 = 6.00x10^-6 C. Where can a third charge be placed, along the line connecting Q1 and Q2, such that it experiences no net force? Give distances relative to Q1 and use a plus sign if the third charge is to the...

The site http://physics.nist.gov/PhysRefData/Handbook/Tables/hydrogentable3.htm shows the intensity of various photon energy values from hydrogen. I was not able to see how this intensity was observed (ie. was it from a specific experiment, or does one simply look at the sun and count photons...

For leptons we have charged leptons electron, muon, tau and uncharged leptons electron neutrino, muon nutrino, tau neutrino. For quarks we have charged quarks pairs down, up and strange, charm and truth, beauty. But we have no neutral quarks. Why? The force carrying particle for the charged...

Hi all, I would like to understand the mechanism by which a neutral impurity can bind an exciton. Because the impurity is neutral the attracation can not be simply electrostatic. I know that there must be a "neutralising electyron (or hole)" in the machanism but things are not clear enough...

I have always been under the impression that the "Live" conductor was the most dangerous conductor. The Live carries 120V (US) 240V (UK) and the Neutral carries 0V, but yet it is still possible to get an electric shock from a Neutral :confused: Why is this possible? Is it because it is...

Is it safe to loop the inverter's output neutral to loop with the mains neutal?? Guys, I need a help on this. I thought that it is rather safe to loop one of the output terminal of the inverter to loop with the mains supply inverter, so that there doesn't arise the need of extra neutral wiring...

Why should the force on a point charge always be toward a neutral conductor? I know this is a simple concept, but I'm having trouble grasping it. Any ideas? Thanks!

An initially neutral conductor contains a hollow cavity in which there is a + 65.0 nC point charge. A charged rod transfers - 75.0 nC to the conductor. Afterwards, what are the charges along the inner surface and the exterior surface? I understand that the charges from the rod are equally...

I have a questions about 120/240v service under balanced loads. When I have a balanced 120v loads the neutral carries no current. I understand the math and vectoral math to this. I am wondering if at molecular level in Quantum Physics if there is actually molecular friction and movement but...

why during the the distribution of electricity to houses neutral wire is connected to Earth wire?

I install and repair coffee and espresso equipment and we sometimes run into electrical problems beyond my knowledge (well versed in household wiring, good with fundamental applications of ohms law, etc. but I'm no physics major!) The issue that comes up most often is dubious grounds, or...

A beam of hydrogen and antihydrogen atoms is accelerated to relativistic velocities by means of a neutral beam accelerator. Identical photodetectors gather and record the photon energies of annihilating H and -H at both ends of the accelerator: where the atoms start; and at the end of the...

I have a sense resistor connected in series with the neutral wire. From the oscilloscope i detect noise of around 500mV - 1V across the sense resistor at high frequencies 60khz- 100khz. I see the noise once the power plug is inserted to the socket, although not switched on(live wire not...

Hi, I'm having quite a time figuring out this problem. I have a weather balloon (well, a choice of several) and a payload of about 2kg. Most people release balloons like this such that they keep climbing until they pop, however I'd like to calculate how much to fill the balloon such that it...

I am wondering if anybody understands the Raymer neutral point formula? I have attached the formula for reference. Even just an example would be good enough. Thanks, Nate

Hello, i'd really need some help with the following questions. 1) Neutral Pion It's quark content is written as: \pi^0=(u\overline{u}-d\overline{d})/\sqrt{2} But the u-quark have a (quite) different mass than the d-quarks. This means that the neutral pion is a superposition of states of...

what are neutral wires and their colours?

My question is how to compute the ratio of cross section (mediate by charge current) of neutrino/ anti neutrino of electron in a nuclei which is made of an equal number of proton's and neutrons The same question to neutral current. I have to deliver soon my work. I hope you can answer...

As the thread title suggests, I was wondering if electrically neutral particles like neutrons can absorb/emit/reflect photons. I don't really have any sort of physics background so I'm not sure this question even makes much sense... but I vaguely remember hearing that photons don't necessarily...

Is there any explanation why the \Xi^0 decays to \Lambda^0 + \pi^0 and not to \Lambda^0 + \pi^-+\pi^+ ?

Homework Statement Well we just learned about Coulomb's Law today but there is something that is bothering me. According to Coulomb's Law the magnitude of the force of attraction between a charged and neutral object is 0. However, the Law of Electrostatics states that a charged and neutral...

can particles be "weak force" charge neutral? In the standard model we have fermions of various electrical charges, including neutral. In some sense, we can consider right handed electrons as "weak force" neutral, however the mass term kind of "mixes" the left and right handed. Is there...

Basically can a neutral pion go to two electrons and two positrons and under what interaction would it do this? I know its defiantly not the strong force, so is it weak or EM? I'm pretty sure its EM but not 100% Thanks

Hi, I have a basic understanding of electrical wiring from when I was in school, and have a question that I have always wondered about that I hope someone could answer. My electrician mate tells me for household wiring its important for active and neutral wires not to be mixed up. That...

Checking Chadwick's statement about the mysterious "neutral radiation"? Hi, I have this interesting little problem about Chadwick's identification of the neutron. As the story goes, Curie and Joliot were firing poloniom-sourced alpha particles at beryllium, causing the emission of a neutral...
