Capacitor reactance algorithm

Capacitive reactance of a capacitor decreases as the frequency across its plates increases. Therefore, capacitive reactance is inversely proportional to frequency. Capacitive reactance opposes current flow but the electrostatic charge on the plates (its AC capacitance value) remains constant.

What is the capacitive reactance of a capacitor?

Capacitive reactance is a complex number with a phase angle of -90 degrees. I hope this helps! The two factors that determine the capacitive reactance of a capacitor are: Frequency (f): The higher the frequency of the AC signal, the lower the capacitive reactance.

How do you calculate the reactance of a capacitor?

We can calculate the reactance of a capacitor at any particular frequency using the expression: where C is the capacitance in farads and f is the frequency. We can see from this that the magnitude of the reactance of a capacitor decreases proportionally with frequency. But hold on! Capacitors are more than ‘frequency-dependent resistors’.

What is reactance of a capacitor at frequency f?

A capacitor with a sinusoidal voltage of frequency f across it will have a sinusoidal current flowing through it. The ratio of the voltage to the current is known as the ‘reactance’ of the capacitor at frequency f. The situation is analogous to that with a resistor, and the unit of reactance is again ohms. And Ohm's Law again applies:

Which AC circuit has a capacitive reactance?

This kind of opposition to the flow of current is called as the capacitive reactance. Therefore, in AC circuits shown below the capacitor also has the capacitive reactance. Capacitive Reactance is only available in capacitor based AC circuits and restricts to the flow of alternating current.

What ohm is the reactance of a capacitor?

As with inductors, the reactance of a capacitor is expressed in ohms and symbolized by the letter X (or X C to be more specific).

How do you measure capacitive reactance?

Capacitive reactance is measured in ohms of reactance like resistance, and depends on the frequency of the applied voltage and the value of the capacitor. where 2π =6.28. The symbol for reactance is X. To specify a specific type of reactance, a subscript is used. In this case, since it's capacitive reactance, the subscript C is used.
