Question

In the microscopic relation for resistivity, what does \(m\) represent?

Options

• The average relaxation time

• The electronic charge

• The electron mass

• The number density of free electrons

Answer 1

In \(\rho=\frac{m}{ne^2\tau}\), \(m\) denotes the electron mass. The other quantities include free-electron number density \(n\), electronic charge \(e\), and average relaxation time \(\tau\).
