The capacitor is

A capacitor is a device used to store electrical energy. The capacitance of a capacitor determines the amount of charging a capacitor can achieve. The measure of the opposition to alternating current by the capacitor is called  Capacitive Reactance.  The unit of Capacitive Reactance is Ohms like resistance. The symbol of Capacitive Reactance is  X C  .

Capacitive Reactance Formula is expressed by

X C   is the capacitance reactance measured in ohms

Calculate the capacitive reactance if 40 mF is connected to a frequency generator of 50 Hz signal.

The capacitance reactance formula is given by

Calculate the reactance of capacitance in an AC circuit wherein the input signal has a frequency of 100 Hz and a capacitor has a capacitance of 1000mF in a circuit.

The capacitance reactance formula is given by

xc = 1 / 2 x 3.14  x 100 x 1000 x 10 -3

Hence, the capacitive reactance is 1.5 x 10 -3 Ω
