Question

resistance of a uniform metallic conductor is inversely proportional o the area of cross section. Explain ​

Answer 1

Answer:

Hola ..

Here is your answer mate_______☺️

Explanation:

Also the resistance of a conductor is inversely proportional to its cross-sectional area (A) as R ∝ 1/A. Thus doubling its cross-sectional area would halve its resistance, while halving its cross-sectional area would double its resistance.

Answer 2

Answer:

Hi there

Explanation:

From this, we conclude that the resistance of a conductor is directly proportional to its length (l) for constant cross-sectional area. Therefore, R∝L. We notice that the resistance was more when the cross - section area was less.
