When reverse bias in a junction diode is increased, the width of depletion layer -

For a reverse bias P-N junction-

In which case is the junction diode is not reverse bias-

Assertion (A): When a p-n junction diode is reverse biased, a feeble reverse current flows known as reverse saturation current Reason (R ): In reverse bias condition, the minority carries can cross the junction.

In the case of a p-n junction diode, if the reverse bias is very high, there is a sudden large increase in current. In this case the value of reverse bias voltage is known as
