Zener diode is used to regulate the voltage supply because, while using a Zener diode

Options

  1. Avoltage remains constant, even when current varies much
  2. BBoth voltage and current remain constant
  3. Cvoltage varies much, but current remains constant
  4. DBoth voltage and current vary together

Correct answer

A. voltage remains constant, even when current varies much

Step-by-step solution

In a Zener diode, voltage across it remains constant even when current varies much or wide range. This property of the Zener diode is used to regulate the voltage supply.
