What is the reactance of a 25 mf capacitor when the applied frequency is 400 hz?

The Reactance of a Capacitor is the resistance it has when alternating current (A/C) with a specific frequency (f) passes through it. This is measured in ohms (Ω) and its formula is:

  (1)

Where:

is the Reactance in ohms (Ω)

is the frequency of the alternating current in Hertz ()

is the Capacitance of the Capacitor in Farad ()

In this case we have a 25 mF capacitor with an applied frequency of 400 Hz.

Note

Well, with the given data we have to solve (1):

Then:

XC=0.0159 Ω   This is the Reactance of the Capacitor
