AC Circuits
There is an inverse relationship between current and resistance, so the capacitive reactance is inversely proportional to the capacitance and the frequency: A capacitor in an AC circuit exhibits a kind of resistance called capacitive reactance, measured in ohms. This depends on the frequency of the AC voltage, and is given by:

Difference Between Resistance and Reactance
Key Differences Between Resistance and Reactance. The resistance is the obstacle in the flow of current in an electrical circuit due to resistor. While reactance is the opposition to the charging current due to either inductor or capacitor. Resistance is the property associated with both ac and dc circuit. However, reactance to the property is ...

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 …
AC Capacitor Circuits | Capacitive Reactance And Impedance
The reactance of a 0.1 μF capacitor as the frequency is varied can be seen in Figure 3. As frequency is changed to 50, 100, 1000, and 5000 Hz, each reactance is computed using the formula for capacitive reactance (capacitor impedance). Notice how the reactance on the graph approaches zero as the frequency heads toward infinity. Figure 3. As ...

What''s the relationship between susceptance and reactance?
Impedance consists of a real part (reistance) and an imaginery part (reactance). Admittance, defined as the reciprocal of impedance, also has a real part (conduction) and an imaginery part (susceptance). If you have a pure reactance, for which the resistance is 0, then the formula reduces to admittance = 1/jX, where X is the …
