Question
In the case of p-n junction diode at a high value of reverse bias voltage, the current rises sharply. The value of reverse bias voltage is known as
Options:
A .  cut-off voltage
B .  zener voltage 
C .  inverse voltage
D .  critical voltage
Answer: Option B
:
B
In reverse bias of p-n junction when a high voltage is applied, electric breakdown of junction takes place, resulting in a large increase in reverse current. This high voltage applied is called zener voltage.
