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:

The correct answer is option (C) Increases with increase in area

Explanation:

We know that, equation of a parallel plate capacitor is given by

C = ε₀ A / d

This implies that,

C ∝ A or

C is directly proportional to A

Hence, if Area increases, capacitance also increases

            if area decreases, capacitance also decreases

C ∝ 1 / d or

C is inversely proportional to d

Hence, if distance between plates increases, capacitance decreases

            if distance between plates decreases, capacitance increases
