A 100 W bulb is connected to an AC source of 220 V, 50 HZ . Then the current flowing through the bulb is

A

`5/11A`

B

`1/2A`

C

`2A`

D

`3/4A`

Text Solution

Verified by Experts

The correct Answer is:
A
Here,
Power of the bulb , P = 100 W
rms value of voltage , `V_(rms)=220Hz`
Frequency of AC source , `upsilon=50Hz`
The current flowing through the bulb is
`I_(rms) =P/V_(rms)=(100W)/(220V)=5/11A`
