Zener Diode as a Voltage Regulator: Practice Problem & Solution

Zener diode is used as: (1999)
Half wave rectifier
Full wave rectifier
A.C. voltage stablizer
D.C. voltage stablizer

Solution Explained:

To solve this problem, we apply the core principles of Zener Diode as a Voltage Regulator. Understanding the underlying formula is key to arriving at the correct answer below:

When connected in reverse bias in parallel with a load, a Zener diode provides a constant DC output voltage regardless of minor fluctuations in the input DC voltage or load current, functioning perfectly as a D.C. voltage stabilizer.
