Question

Write SI unit of conductivity.

Answer 1

1. The conductivity of a material is simply the reciprocal of its resistivity which is denoted by ($\sigma$).
2. The relation between resistivity and conductivity is $\sigma =\frac{1}{\rho }$ Here, $\rho =resistivityofmaterial.$
3. SI unit of conductivity is the reciprocal of ohm-meter ${(\Omega -m)}^{-1}$ or Siemens per meter (S/m).
