Question: What is the effect of increasing the distance between the plates of a parallel plate capacitor on its capacitance?

Options:

1. Capacitance increases
2. Capacitance decreases
3. Capacitance remains the same
4. Capacitance becomes zero

Correct Answer: Capacitance decreases

Solution:

Capacitance (C) is inversely proportional to the distance (d) between the plates. Increasing d decreases C.
