CAPACITANCEBasic AC Reactive Components2. Current flowing in the circuitIEX_{C}120265.4I0.452 amps3. Phasor diagram showing current leading voltage by 90° is drawn in Figure 4b.SummaryCapacitive reactance is summarized below.Capacitive Reactance SummaryOpposition to the flow of alternating current caused by capacitance is calledcapacitive reactance (X_{C}).The formula for calculating X_{C} is:X_{C}12pfCCurrent (I) leads applied voltage by 90^{o} in a purely capacitive circuit.The phasor diagram shows the applied voltage (E) vector leading (below) thecurrent (I) vector by the amount of the phase angle differential due to therelationship between voltage and current in a capacitive circuit.ES-08 Page 8 Rev. 0
