Q. In case of a $p - n$ junction diode at high value of reverse dias, the current rises sharply. The value of reverse bias is known as
A) Cut-off voltage
B) Zener voltage
C) Inverse voltage
D) Critical voltage
Explanation
(b) In reverse bias of $p - n$ junction when high voltage is applied, electric break down of junction takes place, resulting large increase in reverse current. This high voltage applied is called zener voltage.
