VAR - Volt Ampere Reactance (Units of reactive power).

Please can anyone explain the derivation of P=V^2/Xc?

Xc=1/wc.
w=2*pi*f.
Reactive power Q=Vrms/Xc.
w=2*pi*f.
Reactive power Q=Vrms/Xc.

I didn't understand please tell me easy way.

Find out
Xc=1/2*3.142*f*c
then
P=V^2/Xc
Xc=1/2*3.142*f*c
then
P=V^2/Xc
