A wire of resistance 10 ohm and length l draws 2 ampere of current now the wire is folded so that is length is becoming half what will be the resistance and amount of current drawn by folded wire....plz and fast

Answer»

Length of a WIRE is DIRECTLY proportional to resistance and current. So when length of the wire gets doubled/half the resistance and current also GET doubled/half. so here resistance becames 5 ohm and current becames 1 AMPERE
