Question

The mobility of charge carriers increases with increase in the average collision time increase in the electric field increase in the mass of the charge carriers decrease in the charge of the mobile carriers

Answer 1

The mobility of the charge carriers increases with increase in the electric field

Option B.

Explanation:

• when there is an increase in the electric field at a particular point then the force which is exerted to the charge carriers increases. As a result of this there is drifting of the charge carriers at a very fast rate.

• In addition to this if the mass and the average collision time increases then there is decrease in the conduction of the electricity. hence only the change in the electric field will result in change of the mobility of the charge carriers.
