The dominant mechanisms for motion of charge carriers in forward and reverse biased silicon P-N junction are

Assertion:The dominant mechanism for motion of charge carriers in forward and reverse biased silicon P-N junction are drift in both forward and reverse biase. Reason: In reverse biasing, no current flow through the junction.

Explain (i) forward biasing (ii) reverse biasing of a P-N junction diode. With the help of a circuit diagram, explain the use of this device as a half wave rectifier.

In V - I characteristics of p-n junction in reverse biasing results in

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.

No biase is applied to a P-N junction, then the current
