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.

AI Customer ServiceCapacitors are frequently used in AC circuits, most commonly as filters. Capacitors contribute capacitive reactance when used in an AC circuit. The frequency-dependent nature of capacitive reactance allows circuit designers to carefully choose a capacitor.
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?
When a pure capacitor is connected to AC source, a changing value of the applied voltage causes the capacitor to charge and discharge alternatively. The charge that flows through the capacitor is proportional to the capacitance (size of the capacitor) and the applied voltage across the capacitor. It can be expressed as Q = C V V= Q / C Where
The value of this current is affected by the applied voltage, the supply frequency, and the capacity of the capacitor. Since a capacitor reacts when connected to ac, as shown by these three factors, it is said to have the property of reactance — called capacitive reactance.
Capacitors in AC circuits are trickier than DC. This is due to the alternating current. In AC circuits capacitors resist the current. The capacitive reactance is the capacitor resisting the sinusoidal current and is symbolized by XC. Since it is resisting the flow of current the unit for capacitive reactance is ohm.
Without resistance in the circuit, the capacitance charges according to the rate of change of the applied voltage. That means that when the voltage changes the most, the current in the capacitor will be the greatest. When the voltage reaches its maximum value, the current will be zero, but as the voltage decreases, the current changes direction.
