Question

Why photodiode used in Revers Bias because -

(1) Small change in majority charge carrier produces high value of current in reverse bias.

(2) Small change in minority charge carrier produces high value of current in reverse bias.

(3) Small change in majority charge carrier produces low value of current in reverse bias.

(4) Small change in minority charge carrier produces low value of current in reverse bias.

Answer 1

Correct option is (2) Small change in minority charge carrier produces high value of current in reverse bias.
