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 ohms just like resistance (R). Capacitive reactance can be calculated using this formula: X_C=frac{1}{2pi f C}

Step 2: Find the Capacitive Reactance. 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 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 ...
Capacitors and Capacitive Reactance. Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.44.
