Question

Which relationship connects conductivity and resistivity?

Options

• \[\sigma=\frac{1}{\rho}\]

• \[\sigma=\rho\]

• \[\rho=E_g\]

• \[\sigma=\frac{1}{E_g}\]

Answer 1

Conductivity and resistivity are reciprocals: \[\sigma=\frac{1}{\rho}\]. A lower resistivity therefore corresponds to a higher conductivity.
