Question

The magnitude of the drift velocity per unit electric field is known as ……… 

Hint:

{Mobility} (\( \mu \)) is the measure of how quickly electrons respond to an applied {electric field}. It is given by \( \mu = \frac{v_d}{E} \).

Answer 1

Step 1: Understanding Drift Velocity and Mobility
Drift velocity (\( v_d \)) is the average velocity acquired by electrons in a conductor under the influence of an electric field.
Mobility (\( \mu \)) is defined as the ratio of drift velocity to the applied electric field (\( E \)): \[ \mu = \frac{v_d}{E} \] Step 2: Explanation
Mobility represents how easily electrons move in response to an electric field.
It is measured in \({m}^2/{V·s}\).
A higher mobility means that charge carriers move faster for a given electric field.
