A 220 V AC supply is connected between points A and B . What will be the potential difference V across the capacitor ?

A

200 V

B

110 V

C

0 V

D

`220 sqrt(2) V`

Text Solution

Verified by Experts

The correct Answer is:
D
Capacitor once gets charged upto maximum potential. After that for any other lesser value of `p.d` across `A` and `B` diode is reverse biased and it does not allow charged to flow in opposite direction.
From `V_(rms)=(V_(max))/(sqrt(2))`
`rArr V_(max)=V_(rms) sqrt(2) =220 sqrt(2)` volts.
