So we now know that capacitors oppose changes in voltage with the flow of electrons onto the plates of the capacitor being directly proportional to the rate of voltage change across its plates as the capacitor charges and discharges. Unlike a resistor where the opposition to current flow is its actual resistance, the.

The alternating current through a capacitor leads the capacitor terminal voltage by 90o as shown in the figure below.
The rate of change of voltage across the capacitor decides the flow of current through the capacitor. Capacitors along with resistors and inductors help to build very complex AC circuits in many electronic applications. Let us discuss the behavior of AC circuit with capacitance in brief. What Are AC Capacitive Circuits?
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.
AC (alternating current) capacitive circuits are electrical circuits that contain capacitive elements and operate with alternating current. Capacitors are passive electronic components that store and release electrical energy in the form of an electric field between two conducting plates separated by an insulating material, called a dielectric.
From the above equation, capacitive reactance of a capacitor in an AC circuit is the function of frequency and capacitance. The capacitive reactance decreases with increasing frequency which results more current to flow through the circuit. Similarly, decreasing frequency increases the reactance that results the decrease of current flow.
The AC impedance of a capacitor is known as Reactance and as we are dealing with capacitor circuits, more commonly called Capacitive Reactance, XC Capacitance in AC Circuits Example No2. When a parallel plate capacitor was connected to a 60Hz AC supply, it was found to have a reactance of 390 ohms.
