Hz
Capacitive Reactance (Xc)
15.92 Ω
Capacitive Reactance (Xc) vs Capacitance
Capacitive Reactance
Xc = 1 / (2 x pi x f x C)
Reactance decreases with frequency: capacitors pass high frequencies and block low frequencies (DC).
Example Calculation
10 uF capacitor at 1 kHz.
- 01C = 10 uF = 0.00001 F
- 02Xc = 1 / (2 x pi x 1000 x 0.00001)
- 03Xc = 1 / 0.06283 = 15.92 ohms
