Capacitors and Capacitive Reactance. Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.46. The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance.
The combined effect of resistance (R), inductive reactance (X_L), and capacitive reactance (X_C) is defined to be impedance, an AC analogue to resistance in a DC circuit. Current, voltage, and impedance in an RLC circuit are related by an AC version of Ohm''s law:
We refer to this opposition as "reactance" rather than "resistance" because it is non-dissipative in nature. In other words, reactance causes no power to leave the circuit.

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 ...
As the capacitor charges or discharges, a current flows through it which is restricted by the internal impedance of the capacitor. This internal impedance is commonly known as Capacitive Reactance and is given the symbol X C in Ohms.. Unlike resistance which has a fixed value, for example, 100Ω, 1kΩ, 10kΩ etc, (this is because resistance obeys Ohms Law), Capacitive …
The following calculations can be used to calculate capacitance of a single phase capacitor commonly used on medium and high voltage capacitor banks. Use formula F1 when frequency and the capacitive reactance is are known. Use Formula F2 when the capacitor voltage and kvar and frequency are known.
Step 4: Calculate the capacitive reactance. For instance, consider a capacitor with a capacitance (C) of 0.002 F and connected to a circuit with a frequency (f) of 5000 Hz: Capacitive Reactance (XC) = 1 / (2π × 5000 Hz × 0.002 F) XC ≈ 15.92 Ω. Therefore, the capacitive reactance of the given capacitor is approximately 15.92 ohms (Ω).

Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.
