Expert Answer
A Zener diode is used as a voltage regulator. The circuit arrangement consists of RS a suitable resistance joined in series of input unregulated voltage Vi so as to control current flowing through Zener with in a safe limit. RL is a load resistor across which regulated output voltage VZ is obtained.
