Question

The resistivity of two conductors "A" and "B" are 1.62 X 10² m and 5.20X10-8 m
respectively which of them is used in

i) Transportation of electricity ii) The making of heating coils ? Why?​

Answer 1

$\tt\red{Answer:}$

(i) Conductor A

(ii) Conductor B because it's resistivity is more than Conductor A so it will resist more electricity .
