Question

The resistivity of iron is 10.0 x 10-8 Ωm, that of silver is 1.60 x 10-8Ωm and that of mercury is 94.0 x 10-8Ωm. a) Which among iron and mercury is a better conductor? b) which material is the best conductor?

Answer 1

Answer:

Resistivity of iron=10.0×10^-8

Resistivity of mercury 94..0×10^-8

A.Resistivity of mercury is more than that of iron.so iron is a better conductor than mercury

b.silver is lowest among the listed materials.hence ,it is a best conductor
