Capacitive Reactance Calculator

Find a capacitor's reactance at a given frequency.

Calculated Output

Capacitive reactance (Ω) 265.26

Formula: Xc = 1 ÷ (2π·f·C)

Step-by-Step Breakdown

1. Values used:

2. Frequency = 60 Hz

3. Capacitance = 10 µF

5. Capacitive reactance = 265.26Ω

Did this calculator solve your problem today?

The math behind it

Xc = 1 ÷ (2π·f·C). It falls as frequency rises, so capacitors pass high frequencies more easily.

60 Hz, 10 µF → about 265 Ω.

Why does it block DC?

At 0 Hz the reactance is infinite, so no steady DC flows.
