How does the mobility of electrons in a conductor change, if the potential difference applied across the conductor is doubled, keeping the length and temperature of the conductor constant ?

Explanation

To solve the question of how the mobility of electrons in a conductor changes when the potential difference is doubled while keeping the length and temperature constant, we can follow these steps:

### Step 1: Understand the Definition of Mobility
Mobility (\( \mu \)) of electrons in a conductor is defined as the ratio of drift velocity (\( V_d \)) to the electric field (\( E \)):
\[ \mu = \frac{V_d}{E} \]
