a wire of resistivity 10 ohm.m is stretched to double its length. what is its new resistivity? what happens to the current in a circuit if its resistance is doubled?

Answered by ponnuchinnu86

Answer:

The resistance of a conductor is directly proportional to its length (L) as R ∝ L. Thusdoubling its length will double its resistance, while halving its length would halve its resistance.
