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
Reading of ammeter `=I_(rms ) =(V_(rms))/(X_C)=(V_(0) omega C)/(sqrt(2))`
`=(200sqrt(2) xx 100x(1 xx 10^(-6)))/(sqrt(2))=2 xx 10^(-2) A`
`= 20 mA `
