## 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).

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.
