Question

Zener diode is used to regulate the voltage supply because, while using a zener diode (A) voltage remains constant, even when current varies much (B) both voltage and current remain constant (C) voltage varies much, but current remains constant. (D) both voltage and current vary together.

Tardigrade Admin · Accepted Answer

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

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

voltage remains constant, even when current varies much

both voltage and current remain constant

voltage varies much, but current remains constant.

both voltage and current vary together.
