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

Options

  1. Alarge volume of current
  2. Ba constant voltage
  3. Ca current that is increasing without any change in applied voltage
  4. Dall of the above

Correct answer

B. a constant voltage

Step-by-step solution

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
