A given alternating current has an rms value of 5.6 ampere. If this current flows in a circuit containing `10 Omega` of resistance in series with `20 Omega` of inductive reactance, the power consumed in the circuit will be

A

`313.6 W`

B

`940.8 W`

C

`627.2 W`

D

`168 W`

Text Solution

Verified by Experts

The correct Answer is:
A
Inductance does not consume power
`P_(av) = I_("rms")^(2) R = (5.6)^(2) xx 10 = 313.6 W`
