Question:

Zener diode is used as –

Options:

Half wave rectifier

Full wave rectifier

ac voltage stabilizer

dc voltage stabilizer

Correct Answer:

ac voltage stabilizer

Explanation:

For a wide range of values of load resistance, the current in the zener diode may change but the voltage across it remains unaffected. Thus the output voltage across the zener diode is a regulated voltage.
