Customer ServiceCapacitive Reactance (Xc): This is the opposition offered by a capacitor to the flow of AC current. It’s inversely proportional to the frequency of the AC signal and the capacitance of the capacitor. Xc = 1 / (2πfC) where: In summary, while a capacitor doesn’t have a fixed resistance, its impedance varies with the frequency of the AC signal.
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.
However, if we apply an alternating current or AC supply, the capacitor will alternately charge and discharge at a rate determined by the frequency of the supply. Then the Capacitance in AC circuits varies with frequency as the capacitor is being constantly charged and discharged.
As you can see, the capacitive reactance is inversely proportional to the frequency and capacitance. This means that at higher frequencies, the capacitor offers less opposition to the flow of current. In DC circuits, a fully charged capacitor acts as an open circuit, effectively blocking the flow of direct current.
We know that the flow of electrons onto the plates of a capacitor is directly proportional to the rate of change of the voltage across those plates. Then, we can see that for capacitance in AC circuits they like to pass current when the voltage across its plates is constantly changing with respect to time such as in AC signals.
Their size varies based on application, with factors like voltage, current ripple, temperature, and leakage current influencing the selection. Capacitor size selection is crucial for circuit assembly and performance variation. Let’s discuss capacitor size and the parameters that influence it in this article.
