Not in JEE Advanced syllabus

When the Zener diode is used as a voltage regulator, it is connected in

(A)forward bias and in parallel with load.
(B)reverse bias and in series with load.Correct
(C)forward bias and in series with load.
(D)forward bias and in series with load.

Answer: (B)

Solution

A Zener diode works as a voltage regulator in its reverse breakdown region: it is connected in reverse bias, in parallel (shunt) with the load, with a series resistor to limit the current. In breakdown the voltage across the Zener (and hence across the load) stays almost constant even if the input
