What is the resistance to be connected in series with a condenser of a capacity `5muF` so that the phase difference between the current and the applied voltage is `45^(@)` when the angular frequency of applied voltage is 400 rad/s ?

A

`250Omega`

B

`400Omega`

C

`500Omega`

D

`600Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`tanphi=(1)/(omegaCR)`
`R=(1)/(omegaC tanphi)=(1)/(400xx5xx10^(-6)xxtan45)`
`=500Omega`
