Question

The capacity of a parallel plate capacitor depends on.
A. metal used to make the plates
B. thickness of plates
C. potential applied across the plates
D. area of plate

Answer 1

Capacitor formula is $C = \dfrac{{k{\varepsilon _0}A}}{d}$ utilize this to guess the answer. A capacitor is a device that is used to store charges in an electrical circuit. A capacitor works on the principle that the capacitance of a conductor increases appreciably when an earthed conductor is brought near it. Hence, a capacitor has two plates separated by a distance having equal and opposite charges.

Complete step by step answer: A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance.
The amount of charge Q a capacitor can store depends on two major factors : First, the voltage applied and second, the capacitors physical characteristics, such as its size.
Now, according to the question.
We have the formula of the capacitor.
$C = \dfrac{{k{\varepsilon _0}A}}{d}$ …(1)
Where = vacuum permittivity
k = coulomb's law constant
A = area
d = distance
So, from equation (1), we case inter that the capacity of a parallel plate capacitor depends on the area of plate.

So, the correct answer is “Option D”.

Note: In this type of question we need to know the proportionality of each thing given in the question or in the equation is either it is enessily or directly proportional. Capacitor Bank is an economical method of reducing High reactance of high and extra high voltage lines. And It controls the voltage level supplied by reducing or eliminating the voltage drop and increasing power transfer Power system.
