Question

A given lenght of wire is doubled of itself and this process is repeated again by what factors does the resistance of the wire change ​

Answer 1

it changes by temp, length ,material of conductor, and area of cross section

Answer 2

Answer:

The length of wire is doubled on itself and so the area get reduced to half.

The resultant resitance will be 4 times.

The process is repeated and therefore the resistance will increase by 4 times. The total resistance will be increased to 16 times.
