Which of the following is the best electrical consucting metals?

A

Plotonium

B

Copper

C

Silver

D

Aluminium

Text Solution

Verified by Experts

The correct Answer is:
C
There is a difference of `10^(2)` in conductivity between the best electrical conducting metal (silver) and the worst (plutonium). But even plotonium has an electrical condutivity about `10^(5)` times better than the best conducting nonmetallic element.
