Capacitive Reactance

<^< Reactance | Course Index | Worksheet: Capacitive Reactance >^>

Capacitive reactance is inversely proportional to the frequency of the applied alternating current and can be determined from the following formula:

XC = 1 / 2πfC

where XC is the reactance in Ω, f is the frequency in Hz, and C is the capacitance in F.
