Question

The zener diode normally operates under reverse bias condition, the major use of this fact is in the applications where we require (A) large volume of current (B) a constant voltage (C) a current that is increasing without any change in applied voltage (D) all of the above

Tardigrade Admin · Accepted Answer

In reverse bias, once Zener diode attains the breakdown voltage, there is no change in voltage across the diode even if we change the current in the circuit by changing the position of rheostat and that's why the voltage across Zener diode is constant <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-vmx1wvfbcnml.png" />

Q. The zener diode normally operates under reverse bias condition, the major use of this fact is in the applications where we require

large volume of current

a constant voltage

a current that is increasing without any change in applied voltage

all of the above
