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

`17 A`

B

`1.7 A`

C

`1.7 mA`

D

`2.7 A`

Text Solution

Verified by Experts

The correct Answer is:
B
Here, `C = 30xx10^(-6)F, V_("rms")=150V, upsilon = 60 Hz`
Capacitive reactance
`X_(C )=(1)/(omega C)=(1)/(2pi upsilon C)=88.46 Omega`
`I_("rms")=(V_("rms"))/(X_(C ))=(150)/(88.46)=1.7 A`
