In summary, a capacitor in an AC circuit allows for the flow of alternating current and stores energy in the form of an electric field. It consists of two conductive plates separated by an insulating material, and as current flows through it, the capacitor charges and discharges, contributing to the overall energy flow in the circuit.

Capacitors provide a phase delay between the current and voltage. Current leads the voltage by 90 degree. We add more energy to a capacitor by pushing electrons in one side (and pulling the same number of electrons out the other side). The voltage ("pressure") across the capacitor can be used to calculate how much energy is
The delayed introduction of DLCs was caused by a limited market for capacitors that could only store charge but performed poorly at their other main task: filtering voltage ripple ().The typical resistor-capacitor (RC) time constant for a DLC is ~1 s—far too long to be useful for the common application of 120-Hz filtering (8.3 ms
