KVA is the product of volts and ampere in terms of thousands. If the voltage provided to a load is 110 and if the load is taking 10 ampere, the Power is taken by the load is 1100 volt ampere or 1.1KVA ok? P=voltage x ampere / 1000.
1 KVA = 1000 Watts or 1 KW for resistive loads.
in case of motors and threephase motors, there is another calculation.

You know about the equation
power dissipated in a utility = the voltage across it X the current through it?
Kilovolt-ampere is the unit formed on the left side of this equation when you use kilovolt as the unit for voltage and ampere the unit for current. Frankly speaking, KVA is a unit of power.

A very strange things occurs in an AC circuit when you try to supply a non-purley resistive load with power. The total power which you should supply from the source is not equal to the "active power" that is dissipated in the load. There is a kind of power called Reactive power, which is continuously exchanged between the source and the load. The total power (sometimes called the complex power S) is the direct multipication of voltage and current phasors. They suggested the use of the unit (VA) to reflect the direct multiplication). Reactive power is measured in VARs (Volt Ampere Reactive) and active power is measured in watts. KVA is simply one thousand VA.

"Kilo Volt Ampere denotes the amount of voltage taken"
Er, no. It is the power, or more correctly the reactive power, taken.
You should read your book again.
And the abbreviation is kVA - with a lower case k.

Kilo Volt Ampere denotes the amount of voltage taken by the machine to do a particular work. This unit is used in large machines and so the unit is almost always in kilo.
