What happens to the drift velocity of electron and to the resistance if length of conductor is doubled keeping potential differnece unchanged ? |
| Answer» Solution :`v_(d)=(EE)/(m) TAU=(eV)/(ml)* tau [ E=(V)/(l)]`keeping V constant, if l is DOUBLED, `v_(d)` is halved. Again keeping area constant. If length is doubled, if R will be doubled `[R alpha,1` if a is constant]. | |
