Which category do the two identified types belong to?

Explanation:
Energy sources in a circuit are devices that provide power by converting stored energy into electrical energy. The two identified types share this role because they supply voltage and current to the circuit over time, acting as energy sources rather than merely storing or directing energy. That’s what makes them batteries. Resistors only limit or dissipate energy and don’t generate it. Capacitors store energy briefly in an electric field and discharge quickly, but they don’t provide sustained power the way a battery does. Diodes control the direction of current and behave as nonlinear elements, not as energy sources.
