Materials and Components

Q1:

Electrical conductivity of metals expressed in ohm-1 m-1 is of the order of

A 1010

B 105

C 10-4

D 10-6

ANS:B - 105

Conductivity is reciprocal of resistivity. Since resistivity of metals is around 10-7 ohm-m, conductivity is about 107 ohm-1 m-1. So 105 is the nearest value.
