Answer:-

The resistance of wire depends upon several factors:

1. The length of the wire – increasing the length increases the resistance.

2. The thickness of the wire – increasing the thickness decreases the resistance.

3. The temperature of the wire – increasing the temperature increases the resistance.

Answer:

Resistance of a conductor directly depends upon Length of the wire L Inversely 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.
