Answer / guest

kvar denotes the units of reactive power and it is given by


Q=V*V/X


where v denotes voltage and x denotes capacitive reactance


and capacitive reactance is given by



x=1/(2*pi*f*c)
f=frequency and pi=22/7 and c= capacitance for which unit
is farad

Answer / venkat

calculate the Capacitve reactance (Xc) = V/I
Then apply the formula C ( in Farads) = 1/2*3.414*F*Xc
