Asked by Annoyingmous

A circuit consists of a resistor of R=7 Ω, a capacitor of C=7 μF, and an ideal self-inductor of L=0.04 H. All three are in series with a power supply that generates an EMF of 5sin(ωt) Volt. The internal resistance of both the power supply and the inductor are negligibly small. The system is at resonance.

(a) What is the time averaged power (in Watts) generated by the power supply?


We decrease the frequency of the power supply to a value for which the reactance (1ωC−ωL) becomes equal to R; the maximum EMF remains 5 V.

(b) What now will be the time averaged power (in Watts) generated by the power supply?
