Unit of electrical conductivity is
1 ohm
2 siemen
3 \(\mathrm{m} / \mathrm{mho}\)
4 \(\mathrm{mho} / \mathrm{m}\)
Explanation:
D Resistivity and conductivity are interrelated Conductivity is the inverse of resistivity. According to this is easy to express one in terms of the other. \(\sigma=\frac{1}{\rho} \text { unit } \mathrm{mho} / \mathrm{m} \text { or siemen } / \mathrm{m}\)
