A diode is connected to 200 V (rms) ac in series with a capacitor as shown in figure. The voltage across the capacitor is

A

220 V

B

110 V

C

311.1 V

D

`200/(sqrt2)V`

Text Solution

Verified by Experts

The correct Answer is:
D
The diode D will conduct for positive half cycle of a.c. supply because this is forward biased. For negative half cycle of a.c. supply , this is reverse biased and does not conduct . So output would be half wave rectified and for half wave rectified out put
`V_(rms)=V_0/2=(200sqrt2)/2=200/sqrt2`
