Which components of a circuit are associated with the loss of electrical energy?

1. Only resistors
2. Only capacitors
3. Only inductors
4. Resistors, capacitors, and inductors

In an AC circuit energy is continually being stored by the circuit and then given back to the circuit. Capacitors store energy in the electric field between the capacitor plates. Inductors store energy in the magnetic field.

The only components associated with energy loss in an AC circuit are the resistors.
