Assertion (A): When reverse voltage across a p-n junction is increased, the junction capacitance decreases.

Reason (R): Capacitance of any layer is inversely proportional to thickness.

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

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

A is true but R is false

A is false but R is true

Answer : Option A

Explanation :

Increase in reverse voltage increases the width of depletion layer and decrease of capacitance of layer.
