Capacitive Reactance The Reactance Of Capacitors

Capacitive Reactance The Reactance Of Capacitors The opposition to current flow through an ac capacitor is called capacitive reactance and which itself is inversely proportional to the supply frequency. The concept of capacitive reactance (x c) explains how capacitors oppose alternating current, with its value depending on both frequency and capacitance. as frequency increases, the capacitive reactance decreases, allowing more current to flow.

Capacitive Reactance The Reactance Of Capacitors Capacitive reactance is the opposition that a capacitor offers to alternating current due to its phase shifted storage and release of energy in its electric field.

Although a capacitor is basically an open circuit, there is an rms current in a circuit with an ac voltage applied to a capacitor. this is because the voltage is continually reversing, charging and discharging the capacitor. Like inductors, capacitors produce resistance to the flow of an alternating current. this resistance resulting from capacitance is called capacitive reactance (or capacitor impedance). capacitive reactance is measured in ohms, like dc resistance. as you can see from the formula:.

Capacitive reactance is only available in capacitor based ac circuits and restricts to the flow of alternating current. similar to resistive resistances the capacitive reactancs are also measured in ohm. the reactance is normally denoted by the symbol x. The capacitive reactance is the imaginary part of the complex impedance z c of a capacitive component : zc=rc j×xc. actually, the impedance of a capacitor reduces to – jxc since we have seen previously that the phase shift observed in a capacitive component is 90°. Like resistance, reactance is measured in ohm’s but is given the symbol x to distinguish it from a purely resistive r value and as the component in question is a capacitor, the reactance of a capacitor is called capacitive reactance, ( x c ) which is measured in ohms. The capacitive reactance (xc) of a capacitor reduces when the frequency across its two plates enhances. so, capacitive reactance (xc) is inversely proportional to frequency.
