#10 Power used in a Series RLS Circuit A device may be regarded as a series RLC cir-
cuit with a resistance of 250 N, a capacitance of 25.7 µF, and and inductance of 15.3 µH.
Suppose the device is plugged into wall socket which produces a 60 Hz sinusoidal voltage
where VRMS = 120 V. How much power, averaged over a long time, is consumed by the
device? Hint: remember that
Pav = RMSR and VRMS = IRMSZ
It may be useful, as well, to keep in mind that
1
Z = VR + (Xc – Xµ)² where Xc
wC
XL = wL, and w= 2nF
