Question

What is conductivity of a resistor?

Answer 1

1. Conductivity of a resistor is defined as the reciprocal of the resistivity.
2. Mathematically, $\sigma =\frac{1}{\rho }$ where $\sigma$ is the conductivity of a resistor and $\rho$is the resistivity of a resistor.
3. S.I. unit of conductivity is ${(\Omega -m)}^{-1}$it is also called as Siemens per meter.
