If `V_0` and `I_0` are the peak current and voltage across the resistor in a series `L-C-R` circuit, then the power dissipated in the circuit is `(power factor =costheta)`

A

`(V_0I_0)/2`

B

`(V_0I_0)/sqrt2`

C

`V_0I_0costheta`

D

`(V_0I_0)/2costheta`

Text Solution

Verified by Experts

The correct Answer is:
D
`:'P=V_("rms")I_("rms")costheta`
`=(V_0/sqrt2)(I_0/sqrt2)costheta`
`=(V_0I_0)/2 costheta`
