In the circuit below, the `AC` source the voltage `V=20cos (omegat)` volts with `omega=2000rad//sec`. The amplitude of the current will be nearest to

A

2A

B

3.3A

C

`2//sqrt(5)A`

D

`sqrt(5)A`

Text Solution

Verified by Experts

The correct Answer is:
A
`X_(L)=L omega=10 `
`X_(C)=1/(C omega)=10 `
`X_(L)-X_(C)=0`
So, Z=R=6+4 =10
`I_(0)=V_(0)//Z =2A`
