Assertion (A): A p-n junction has high resistance in reverse direction.

Reason (R): When a reverse bias is applied to p-n junction, the width of depletion layer increases.

A.

Both A and R are true and R is correct explanation of A

B.

Both A and R are true but R is not a correct explanation of A

C.

A is true but R is false

D.

A is false but R is true

Correct answer is A

The increase in reverse resistance is due to widening of depletion layer.
