6 FAQs about [Relationship between the capacitive reactance and current of a capacitor]
What is the difference between capacitance and reactance in AC circuits?
For capacitors in AC circuits opposition is known as Reactance, and as we are dealing with capacitor circuits, it is therefore known as Capacitive Reactance. Thus capacitance in AC circuits suffer from Capacitive Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only.

From points d to e, the capacitor discharges, and the flow of current is opposite to the voltage. Figure 3 shows the current leading the applied voltage by 90°. In any purely capacitive circuit, current leads applied voltage by 90°. Capacitive reactance is the opposition by a capacitor or a capacitive circuit to the flow of current.
What is capacitive reactance?
As reactance is a quantity that can also be applied to Inductors as well as Capacitors, when used with capacitors it is more commonly known as Capacitive Reactance. For capacitors in AC circuits, capacitive reactance is given the symbol Xc.
How do capacitors behave in AC circuits?
Capacitive reactance is inversely proportional to frequency. As the frequency gets lower, the capacitive reactance gets higher. As the frequency gets higher, the capacitive reactance gets lower. This is how capacitors behave in AC circuits. Capacitive reactance is the measure of how a capacitor resists the flow of alternating current.
What is the reactance of a capacitor?
For capacitors, the reactance is called Capacitive Reactance and written as XC. Capacitors charge and discharge faster when the voltage across them changes faster. This means that more current flows when the voltage changes more rapidly. On the other hand, less current flows when the voltage changes slower.
Is capacitive reactance inversely proportional to frequency and capacitance?
It can also be said that if the frequency or capacitance is increased, the opposition to current flow decreases; therefore, capacitive reactance, which is the opposition to current flow, is inversely proportional to frequency and capacitance. Capacitive reactance X C, is measured in ohms, as is inductive reactance.
