Question

7.
The resistivity of two conductors 'A' and 'B' are 1.62 x 10-22 m and
5.20 x 10 * 12 m respectively. Which of them is used in :
(1) Transportation of electricity
(ii) The making of heating coils? Why?​

Answer 1

1. conductor A
2. conductor B because it's resistivity is more than conductor A so it will resist more.
