Question

A circular conductor is made of a uniform wire of resistance 2 X 10^-3 ohm/M and the diameter of the circular conductor is 2 meters then the resistance measured between the ends of the diameter in Ohms.

Answer 1

Given,resistance per metre =2* 10^-3 ohm.

Then ,the resistance between the ends of circular conducter of diameter 2m;.

=2❌2❌10^-3 ohm

=4❌10^-3 ohm

or,

4milli ohm.
