There are two types of energy storage devices used in power supplies: capacitors and inductors. Unlike resistors, ideal inductors and capacitors only store energy, but never dissipate energy.

AI Customer ServiceWhile the voltage across the capacitor does not change once it reaches its maximum value during the steady state, it is essential to understand that voltage fluctuations
AI Customer ServiceWhen capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
So whenever the capacitor is confronted with a change in voltage, it responds by changing its charge. The capacitor counteracts the change in voltage. When the input voltage is rising: "Capacitor stores charge/charges up" applies. When the input voltage is falling: " (If voltage is not constant) capacitor does discharge" applies.
What is not shown is that the input must contain a diode or similar component, so if the input voltage is lower than the capacitor plate voltage then the capacitor does not discharge back into the power supply. (I'm 20 years past A-levels and still find the marking schemes obtuse, they're simplified beyond the point of understanding)
The current through a capacitor is equal to: Non-ideal power supply capacitors have equivalent series resistance and leakage current. Common types for power supply capacitors are aluminum electrolytic, tantalum, multilayer ceramic, film. Aluminum and tantalum types are polarity sensitive.
Power supply filtering: Capacitors smooth out the voltage provided by power supplies, reducing any ripples or fluctuations. They act as a buffer, ensuring a stable and reliable power source for the rest of the circuit components. Timing circuits: Capacitors, in conjunction with resistors, can create precise time delays or oscillations in circuits.
Energy is needed from a power supply or other source to charge a capacitor. A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on:
