RC Circuits

The true power in the given circuit equals ___.

A 48.48 mW

B 296.93 mW

C 280.64 mW

D 96.98 mW

ANS:D - 96.98 mW

First, we need to find value of Xc = 1/2pi * f * c.
Find impedance z = sqrt (R^2 + Xc^2).
I = V/Z.
True power P = VI Cos θ.
θ = tan inv (xc/R) put values in all these formulae we will get the answer.
