The' distance between the plates of a parallel plate capacitor is `d`. A metal plate of thickness `d//2` is placed between the plates. What will `e` its effect on the capacitance.

A

Half

B

Double

C

One fourth

D

Unchanged

Text Solution

Verified by Experts

The correct Answer is:
B
`C.= (in_(0)A)/(d//2) = (2in_(0)A)/(d)= 2C`
