# 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? - Physics

#### Question

Short Note

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?

#### Solution

The mobility of electrons in a conductor is given by the expression, µ = (eτ)/m
As its independent of the applied potential difference, so it will not change if the applied potential difference will be doubled.

Is there an error in this question or solution?
