A Power Capacitor is an electrical device that can store and discharge electric energy. The device consists of one or more pairs of plates, separated by an insulating material (the dielectric), which are attached to two terminals that allow the stored energy to be discharged into a circuit when required. The power capacitor symbol is shown below.
Capacitors in AC circuits are key components that contribute to the behavior of electrical systems. They exhibit capacitive reactance, which influences the opposition to current flow in the circuit. Understanding how capacitors behave in series and parallel connections is crucial for analyzing the circuit's impedance and current characteristics.

When discussing how a capacitor works in a DC circuit, you either focus on the steady state scenarios or look at the changes in regards to time. However, with an AC circuit, you generally look at the response of a circuit in regards to the frequency. This is because a capacitor’s impedance isn’t set - it’s dependent on the frequency.
