Question

On reducing potential across or capacitor it's Capacitance `^(*)`

(A) Decreases (B) Increases (C) Remains constant (D) First increases than decreases​

Answer 1

While reducing potential across the capacitors, its capacitance b) increase.

Explanation:

• In capacitor which  plates the field is constant, but the potential increases linearly.
• The capacitance will always remain constant, hence the geometry of the capacitor remains constant.
• The presence of the dielectric between the plates of the capacitor reduces the voltage.
• Hence, the decrease in the voltage the capacitance will be increased at the time.
• The capacitance of a capacitor does not depend on the charge or potential, it will be depending on the physical parameter of the capacitor.
