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
Solution
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.
