Equations ref{1.8} and ref{1.9} are notable because the reactance is not just a function of the capacitance or inductance, but also a function of frequency. The reactance of an inductor is directly proportional to frequency while the reactance of a capacitor is inversely proportional to frequency. The ohmic variations of a (20 Omega

Capacitance in AC Circuits and Capacitive Reactance

Capacitance in AC Circuits – Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only. Like resistance, reactance is also measured in Ohm''s but is given the symbol X to distinguish it from a purely resistive value. As reactance is a quantity that can also be applied to Inductors as well as Capacitors, when used with capacitors

For capacitors and inductors, this ratio of peak voltage over peak current is frequency dependent. They are called reactance. Both resistance and reactance are measures of how the components oppose the flow of current. The unit of reactance is the same as that of resistance – in ohms. We use the symbol X to represent reactance here.

Calculating Capacitance and Capacitive Reactance

This shows that the reactance of a capacitor in an AC circuit is "inversely proportional" to the frequency of the power source, as shown below. X C = 1 / 2πfC. Where: X C denotes the Capacitive Reactance in Ohms, ƒ is the symbol for the frequency in Hertz and C gives us the AC capacitance in Farads, represented by F. A similar concept to capacitive

Capacitive reactance is the opposition presented by a capacitor to the flow of alternating current (AC) in a circuit. Unlike resistance, which remains constant regardless of frequency, capacitive reactance varies with the frequency of the AC signal. It is denoted by the symbol XC and is measured in ohms (Ω).
