Assertion : For a given applied voltage, conduction current in n-type semiconductor is more than in p-type semiconductors. Reason : Mobility of electrons is greater than that of holes.

Answer»

If both assertion and reason are true and the reason is the correct explanation of the assertion
If both assertion and reason are true but the reason is not the correct explanation of the assertion
If assertio is true statement but reason is false.
If both assertion and reason are false statement

Solution :Electron EFFECTIVE mass is LESSER than hole effective mass. The mobility is proprtional to the carrier RELAXATION TIME and inversly proprtionnal to the carrier effective mass.
