Question

Resistance of conductor is 100 ohm if resistance wire os stretched so that of the wire become doubled.what is new resistance of the wire?​

Answer 1

Answer :-

⭕ Given, Resistance of conductor = 100 ohm

Stretching of wire = 2 times

New resistance = n^2 R

R' = (2)^2 * 100 ohm

R' = 4*100 ohm

R' = 400 ohm
