First take out odd kV= its the Potential difernce (Volt) in Kilo volts
KVA (Apparent power)=vector sum ( kW{active power}+kVAR{Reactive power))

now to tell u in breif in analogous way abot this KVA ,KVAR,KW

suppose we have to take one ball from A to B then

if the path is flat Road the power used is called active power

now if the path is upside of incline road the to take the ball we do extra effort
1) active power work to take ball from A to B
2) reactive power work to take in incline up side (extra work )

but total power used in this case will be greater and work done is same taking ball from A to B, this power is called as apparent power
active and reactive power
