Customer ServiceResistor and capacitor perform different functions in terms of the power in the circuit: resistor – dissipates energy, and capacitor – stores energy. So the instantaneous power from the source is p (t) = V i (t). Current here is i (t) = V – v C (t) R. We already know that for this circuit capacitor voltage is v C (t) = V (1 – e – t R C).

Customer ServiceResistors and capacitors can meet the two key requirements of an energy storage device in electrical circuits: they can be charged quickly, and they can discharge over long terms. (Note: This passage primarily discusses the use of resistors and capacitors in conjunction to achieve quick charging and long-term discharging, not as standalone energy storage devices. However, since the question asks about their potential for energy storage, the passage is still relevant.)
Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
The size of the resistor in a RC circuit affects the capacitance, or the amount of electrical energy a capacitor can store. Until now, the role of this RC combination in electrical energy storage in such circuits has been overlooked.
