Question:

Resistor, capacitor, and inductor in a series across AC generator?

A resistor, capacitor, and inductor are connected in series across an AC generator. Which of the following statements is true? a. All the power is lost in the capacitor.b. All the power is lost in the resistor.c. Power is lost in all three elements.d. All the power is lost in the inductor.

Answer:

If these are the only choices, C is the most correct answer. This is due to an Electrical phenomenon called Impedance. Impedance in AC Circuits because of interaction between Resistors, Capacitors and Inductors is similar to resistance in DC Circuits. Whenever you have all three (resistance, capacitance, inductance) in an AC Circuit you will have currents due to Impedance and therefore all elements cause power to be lost.
