If the distance between the plates of two capacitor is increased then capacitance
Options
(a) increase
(b) decrease
(c) remains constant
(d) first increase then decrease
Correct Answer:
decrease
Explanation:
Capacitance of a parallel plate capacitor is C = ε₀A / d
where A is the area of a plate and d is the distance between the plates.
or, C ∝ 1 / d
In other words when d increase C decreases.
