Question

Choose the correct option:

A Series resistance is connected in the Zener diode circuit to ______.

Options

• Properly reverse bias the Zener

• Protect the Zener

• Properly forward bias the Zener

• Protect the load resistance

Answer 1

A Series resistance is connected in the Zener diode circuit to protect the zener.

Explanation:

Because, on reverse biasing the Zener diode, voltage exceeds the limit voltage of the diode which may destroy the Zener diode, so to protect it from breakdown, a resistance is added in series with it.
