Analog Electronics

Q1:

In a voltage regulator circuit using zener diode the load voltage is nearly constant only if

A zener current is very small

B zener current is very large

C zener current is neither small nor large

D None of the above

ANS:A - zener current is very small

I think option c is the correct answer. If zener current is very small, then diode will not be in breakdown resulting a varying voltage across the load.
