AI Generated Solution

To derive the expression for drift velocity (\( V_d \)) of free electrons in terms of relaxation time (\( \tau \)) and the electric field (\( E \)) applied across a conductor, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the System**: - Consider a conductor with free electrons. When an electric field \( E \) is applied, it exerts a force on the electrons, causing them to drift in the direction opposite to the electric field. 2. **Force on an Electron**: ...
