The resistance of the conductor is 100m/s. If the length of the wire is doubled and the area of cross section is heated, then what will be the resistance of wire

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.
