The AC impedance of a capacitor is known as Reactance and as we are dealing with capacitor circuits, more commonly called Capacitive Reactance, X C Capacitance in AC Circuits Example No2. When a parallel plate capacitor was connected to a 60Hz AC supply, it was found to have a reactance of 390 ohms.
However, they differ because electrical resistance opposes current flow (AC or DC) in conductors and resistors, whereas capacitive reactance applies to capacitors and is specific to AC power. In addition, the reactance of a capacitor is inversely proportional to the frequency, while electrical resistance remains constant as …
Impedance of a capacitor – Capacitive reactance The Impedance of a capacitor (Capacitive reactance) is the measure of the opposition to a change of the electrical current in this component. It can be summarized, in a very general way, that a capacitor lets the high frequencies signals pass and blocks the low frequencies signals. . (including 0 Hz

The interaction between capacitance and frequency is governed by capacitive reactance, represented as XC. Reactance is the opposition to AC flow. For a capacitor: XC = 1/(2πfC) where: Xc is the capacitive reactance in ohms (Ω) f is the frequency in hertz (Hz)
The capacitor''s charge will be: $$ mathrm{ Q = C V_S = C V_m sin(omega t) } $$ And the current will be: $$ mathrm{ i(t)=frac{dQ}{dt} Rightarrow …

But why is the inductive reactance or capacitive reactance phasor on imaginary axis while the resistance phasor is taken on the real axis? What will happen if we take resistance as the imaginary component and reactance as the real component? ... Given that (complex) impedance is defined as the ratio of phasor voltage to phasor …
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, …
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. Reactance is symbolized by the capital letter "X" and is measured in …
