The role of adding reactance to capacitors
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
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: XC = 1/(2πfC)

23.11 Reactance, Inductive and Capacitive
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.
8.3: Reactance, Inductive and Capacitive
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.
Inductors in AC Circuits
Why it Matters: Inductors are frequently used in AC circuits, most commonly as filters ductors contribute inductive reactance when used in an AC circuit. Inductive reactance is frequency dependent, and results in an opposition to current flow. Like capacitors but unlike resistors, inductors do not dissipate energy but rather, store and …

The law also applies to AC current flowing through a resistor. A capacitor also behaves like a resistor against AC current—a property known as capacitive reactance. However, a capacitor does not conduct all forms of AC current in the same way: its capacitive reactance is inversely proportional to the frequency of the AC current.
