Electrical conductivity of metals expressed in ohmâ»Â¹ mâ»Â¹ is of the order of

Electronics and Communication Engineering (ECE) : Materials and Components - Quiz(MCQ)

10âµ

10Â¹â°

10â»â´

10â»â¶

Correct Answer : Option (A) : 10âµ

Explanation : Conductivity is reciprocal of resistivity. Since resistivity of metals is around 10â»â· ohm-m, conductivity is about 10â· ohmâ»¹ mâ»¹. So 10âµ is the nearest value.
