Question

what is the relation between internal resistance resistance and length of the wire​

Answer 1

Explanation:

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.

hope it's help

Answer 2

Internal resistance increases as the length of wire increases.

So internal resistance is directly proportional to the length of wire.
