Question

5.
Find the capacitance of arrangement of 4 plates of Area A at distance d ,
in air as shown.​

Answer 1

The capacitance is $\dfrac{3\epsilon_{0}A}{d}$

Explanation:

Given that,

Number of plate = 4

Area = A

distance = d

We need to calculate the capacitance

Using formula of capacitance

$C=\dfrac{\epsilon_{0}A}{d}$

According to figure,

The lower side of plate 1 and upper side of plate 2 form a capacitor,

The lower side of plate 2 and upper side of plate 3 form another capacitor.

The lower side of plate 3 and upper side of plate 4 forms the third capacitor.

The capacitance of each of the three capacitors is

$C=C_{1}+C_{2}+C_{3}$

Put the value into the formula

$C=\dfrac{\epsilon_{0}A}{d}+\dfrac{\epsilon_{0}A}{d}+\dfrac{\epsilon_{0}A}{d}$

$C=\dfrac{3\epsilon_{0}A}{d}$

Hence, The capacitance is $\dfrac{3\epsilon_{0}A}{d}$
