What is the relationship between resistivity r and conductivity s?

64. What is the relationship between resistivity r and conductivity s?

1. r = s²
2. r = s
3. r = 1/s
4. r = 2/s

Answer

The correct answer is: C) r = 1/s

Explanation

The relationship between resistivity r and conductivity s is that: Conductivity (s) is the inverse (reciprocal) of resistivity (r) i.e., r = 1/s.
