How is mobility (µ) of charge carriers in a conductor defined?

The drift velocity per unit electric field.

The speed of electrons in the absence of an electric field.

The rate of electric charge per unit time.

The energy per unit charge in the conductor.

Mobility (µ) is the drift velocity per unit electric field, indicating how quickly charge carriers can move in response to an applied field.

Option 2 describes electron speed without an electric field, unrelated to mobility.

Option 3 refers to current, not mobility.

Option 4 relates to potential or voltage, not mobility.
