A capacitor of 10muF and an inductor of ...

A capacitor of `10muF` and an inductor of `1` H are joined in series An ac of `100rad//sec` is applied to this combintaion The impedance of the combintaion .

A

`900Omega`

B

`1000 Omega`

C

`1100 Omega`

D

`1200 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A

`X_(L) = omegaL = 100 xx 1 =100Omega`
`X_(C) = (1)/(omegaC) = (1)/(100 xx 10 xx 10^(-6) ) = Omega`
`Z = X_(L) ~ X_(C) = 900Omega`
