Capacitive Reactance Calculator
The calculator computes capacitive reactance based on frequency and capacitance. It supports Hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), picofarads (pF) and microfarads (uF).
XC = 1 / ( 2πFC )
Reactance can be thought of as AC (alternating current) resistance. While a DC (direct current) will charge a capacitor to the value of its voltage source and stop, AC will see a capacitor as a resistive load. With AC, there will be a voltage drop across the capacitor and the current will be limited. The reactance of a capacitor will increase as frequency or capacitance decreases.
