Piece of resistance wire has resistance of 4ohms it is doubled on itself. now its resistance will be

Answers

Answered by WonderGirl

When the length of the wire increases, the resistance of the wire too increase.

Because the current have to travel more distance and hence more obstacles(resistance) will be there.

Hence, on doubling the length of the wire, the resistance gets doubled too.
