4.
As the magnitude of reverse bias is increased, the capacitance of varactor diode
increases
decreases
first increase, then decreases
first decreases then increases
Answer: Option
Explanation:

When magnitude of reverse bias is increased, thickness of depletion layer increases.

Capacitance is inversely proportional to thickness.
