Answer / jack

a var is a unit of reactive power

a farad is a unit of electric capacitance

see convert-units.net

Answer / mgr

Var=VVWC
Where V=Supply voltage
W=2*3.14*F
F=frequency
C=micro farad.

Answer / dan

var = reactive power, microfarad = capacitance
var = reactive current x voltage = (V/Xc) x V
var = V² x 2ЛfC
Where f = frequency (Hz)
C = Capacitance (μF)
Xc = capacitive reactance = 1/(2ЛfC)

Answer / cyclone1537

VARs = V²/ Xc = 2*phi*f*C

VARs =voltampere reactive
V =system voltage
Xc =capactive reactance
phi =3.1416
f =system frequency. hertz
C = capacitance, farad
