### Step-by-Step Solution **Step 1: Define Drift Velocity** Drift velocity is defined as the average velocity that free electrons acquire due to an applied electric field in a conductor. When a potential difference is applied across a conductor, the free electrons, which are in random motion, experience a net force in the direction of the electric field. This results in a small average velocity of the electrons along the direction of the electric field. The drift velocity is denoted by \( V_d \). **Step 2: Explain the Concept of Drift Velocity** ...
