Question

state factors on which resistance of cylindrical conductor depends. How will resistance change if it is stretched so that it's length is doubled?​

Answer 1

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.
