Question

Obtain the formula of the relationship of drift velocity and potential difference.

Hint:

Drift velocity increases linearly with the applied potential difference.

Answer 1

The drift velocity \( v_d \) is related to the applied potential difference \( V \) by the formula: \[ v_d = \frac{e E \tau}{m} \] Since \( E = \frac{V}{L} \), the relationship becomes: \[ v_d = \frac{e \tau}{m} \cdot \frac{V}{L} \]
