A diode is connected to `220V (rms)` `ac` in series with a capacitor as shown in fig. The voltage across the capacitor is

A

`220` V

B

`110` V

C

`311.1` V

D

`(220)/(sqrt(2))V`

Text Solution

Verified by Experts

The correct Answer is:
D
For `+` ve half `to` D `to` FB (ON)
For `-ve` half `to` D `to` RB (OFF)
Output of rectifier `(V_(rms))=(V_(0))/(2)=(200sqrt(2))/(2)=(200)/(sqrt(2))`
