Capacitance

Question

In a parallel plate capacitor of capacitance C, if plate area is doubled and plate separation is halved, the capacitance becomes

Easy

A

2 C
B

C/2
C

$\frac{C}{4}$
D

4 C

Solution

$C = \frac{\in_{0} A}{d} ∴ C^{1} = \frac{\in_{0} (2 A)}{(\frac{d}{2})} = 4 \frac{\in_{0} A}{d} = 4 C$
