What happens during regualtion action of a Zener diode?

A

(a)The current and voltage across the Zener remains fixed.

B

(b) The current through the series resistance( R) changes.

C

( c) The Zener resistnace is constant .

D

The resistance offered by the Zener changes.

Text Solution

Verified by Experts

The correct Answer is:

B, D

When applied voltage approaches zener potential diode breakdown to conduct excess current in series resistance.
