An alternating voltage `E=200sqrt(2)sin(100t)` is connected to a `1` microfarad capacitor through an AC ammeter. The reading of the ammeter shall be

A

10 mA

B

20 mA

C

40 mA

D

80 mA

Text Solution

Verified by Experts

The correct Answer is:
B
`X_(C) = (1)/(omega C) = (1)/( 100 xx 10^(-6)) = 10 ^(4) Omega`
`i_(rms) = (V_(rms))/(X_(C)) = (200 sqrt(2))/(sqrt(2) xx 10^(4)) = 20 m A `
