Question

The capacitance of parallel plate capacitor increase

(A) decrease of its area of plates (B)increase of its distance between plates

(C)increase of its area of plates (D) none​

Answer 1

Answer:

b

Explanation:

increase of its distance between plates

Answer 2

The capacitance of parallel plate capacitor increase due to increase of its area of plates.

Explanation:

The capacitance of parallel plate capacitor is proportional to surface area of plates.

The capacitance of parallel plate capacitor is inversely proportional to distance between plates.

To calculate capacitance having no dielectric, C = ε₀A / d

If capacitance increases, surface area of plates will increase and distance between plates will decrease.

If capacitance decreases, surface area of plates will also decrease and distance between plates will increase.

C = ε₀A / d

where,

C = Capacitance

A = Area of plates

d = distance between plates

ε₀ = Permittivity of air
