But even in electron model of current flow all the electrons in conductor start drifting at once due to application of electric field at one end of conductor which just applied at all points of conductor atonce(because speed of electric field propogation is 3*10^8 so light lights up so fast ie...
Consider proton and electron are separated in space at some finite distance.Now suppose they released then the decrease in potential energy equals kinetic energy but as electrons or protons are accelerated they emit em and lose some gained kinetic energy.Also the mass is another form of...
sir,you are not understanding me in radio transmitter we use oscillator circuits.In which electrons doesn't move with constant drift velocity but they oscillate and so generate em.But even without oscillator circuit i thought there should be production of em. sir please read...
but why electron moving in conductor which is also accelerated can't emit em waves??
Again in second explanation why only accelerating charge and not charge moving with constant velocity produce em? Also what about particle nature of em waves?
I am beginner in physics.I have question that when dc current flow they flow with apparent drift velocity so it appears that it should not emit em waves.But in actual current flow electrons are accelerated due to applied potential and also deaccelerated during collision so even they appear to...
