Question

Zener diode is used as an

• A. Amplifier
• B. Voltage Regulator
• C. Oscillator
• D. Rectifier

Hint:

Zener diodes are commonly used as voltage regulators because they maintain a constant voltage across them in reverse breakdown.

Answer 1

The Correct Option is B

A Zener diode is commonly used for voltage regulation, as it allows current to flow in the reverse direction when the voltage exceeds a certain value, maintaining a stable output voltage.
