As stated earlier, this changing opposition of a capacitor is called capacitive reactance and is inversely related to the source frequency. 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.
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.
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.
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.
Hence in DC voltage, capacitive reactance is very high. As frequency increases, capacitive reactance decreases. This behaviour of capacitor is very useful to build filters to attenuate certain frequencies of signal.
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. Like resistance, reactance is also measured in Ohm’s but is given the symbol X to distinguish it from a purely resistive value.
