A `30 mu F` capacitor is connected to a 150 V, 60 Hz ac supply. The rms value of current in the circuit is

A

1.7A

B

2.05A

C

2.5A

D

25.1A

Text Solution

Verified by Experts

The correct Answer is:
C

`I_(rms) = (V_(rms))/(X_(C)) = (V)/(1//Comega) = VComega `
`= 200 xx 40 xx 10 ^(-6) xx 2pi xx 50`
`= 2.5 A `
