Question

what is the resistance of conductor mention the factors on which the resistance of a conductor depend

Answer 1

1 resistance depend on the length of conductor or wire.
2 resistance depend on the area of cross section
3 resistance depend on the nature of material

Answer 2

Answer.

Resistance of a conductor directly depends upon Length of the wire LInversely depends upon Area of Cross section of the conductor 1/A Nature of material used. Therefore, R=ρ L/A Length of the conductor is double, means you are stretching that given length to double it. As a result, the wire becomes thin due to stretching. So its area of cross section will be halved(Since the volume remains constant). So new resistance RN = ρ 2L/A/2 = 4. ρ.L/A =4R Hence the new resistance will become 4 times.
