Question

What happens to the resistance if a conductor if its length is increased
​

Answer 1

$\huge\mathfrak\purple{Answer}$

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. Also the resistance of a conductor is inversely proportional to its cross-sectional area (A) as R ∝ 1/A.
