1) on the basis of laws of series and parallel resistance prove that the resistance of a conductor is directly proportional to its length and inversely proportional to which area of cross section

Answers

Answered by koushikmkj

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.
