has resistance 'R'. The area of cross section of another conductor of same
material and same resistance but of length 2ľ is​

Answer 1

Answer:

2A

Explanation:

Since resistance is inversely proportional to area of cross section...if L is increased, R also increases, but if A s decreased at the same time, then R remains the same

Answer 2

Answer:

2A
