Question

what happens to the resistance of a conductor when its length is decreased?​

Answer 1

$\huge\bold{Answer:-}$

When the length of a conductor is decreased then the resistance of that conductor also decreases , As the resistance of a conductor is directly proportional to its length (L) as R ∝ L. Thus doubling its length will double its resistance, while halving its length would halve its resistance.

i.e, R ∝ L

where,

R = resistance of the conductor

L = length of the conductor.
