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.
Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
A capacitor stores electrical charge in the form of the electrostatic field in response to an applied voltage. It charges whenever the applied voltage increases (relative to the current-voltage across the capacitor) by allowing a charging current until the voltage across it equals and is opposite to the applied voltage.
Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (8.2.7) (8.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.

When used in a direct current or DC circuit, a capacitor charges up to its supply voltage but blocks the flow of current through it because the dielectric of a capacitor is non-conductive and basically an insulator.
