volt ampere reactive is the unit of reactive power.It is the power which does no useful work but is required to assist in performing work,such as setting up magnetic fields in motors and Transformers.It is also called as imaginary power.It occurs in purely reactive circuit i.e. purely inductive or capacitive.The inductance absorbs the reactive power and capacitance injects the reactive power.In inductance,reactive power is utilised to develop the flux while in the capacitance,the reactive power's function is to store the charge.

What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
What is VAR?
Volt-Ampere Reactive. It is the reactive component of power when the Power Factor is less than unity (1.0). It is usually measured in KVAR - 1000's of VAR.
How volt and amps used in house?
230
What is 70 kVA?
70,000 Volt Amps
How many amps is 4800 watts at 220 volt?
you will need 21.81 amps at 220v
What is the unit of measure for reactive power?
Volt Amps [volts times amps] is used for reactive and apparent power. Watts (dimensionally the same as volt amps) is used to indicate real power.AnswerReactive power is measured in reactive volt amperes (var).
How many amps are in 40 volt amps?
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
What are volt-amps?
Volt-Amp gets its name from Ohm's law, where volts X amps = watts. You will commonly see it abreviated as VA. Also called apparent power. So, when we say volt-amps, we are alluding to a measurement of power. Strictly speaking, VA is not always EXACTLY the same as watts though. In a DC circuit, or an AC circuit where the load is non-reactive (purely resistive), volt-amps are exactly the same as watts. In an AC circuit where the load is reactive, current is not exactly in phase with the voltage, and watts (true power) will be lower than VA. For example, consider a standby power generator like you might buy for a building. It may be rated for 10,000 VA if it is feeding non-reactive loads, like electric heaters and incandescent lamps. BUT, the same generator may have a watt rating of only 8,500, meaning if it is powering a reactive load like motors, flourescent lamps or computers, it is limited to less than 10,000. The difference is called power-factor. In the example above, the power-factor would be 0.85. If you want to lean more (who doesnt?) do a google search for the following terms: true power apparent power power factor reactive power KVAR (kilovolt-amp reactive)It is a measurement of total power. Very similar to watts. Volt-Amps is also known as VA. The formula is: VA = Volts * Amps
What is reactive power in three phases system?
Reactive power occurs in an AC system when it has a load with a poor power factor such as an induction motor. The power delivered is less than the voltage times the current by a factor called the power factor. The real power and the reactive power combine according to Pythgoras, in other words if they are represented by two sides of a right-angle triangle, then the hypotenuse represents the volt-amps. In the equation kW is the power in kilowatts, kVAR is the kilovolt-amps of reactive power, and kVA is the kilovolt-amps: (kW)2 + (kVAR)2 = (kVA)2
How many volt amps in 12 volt battery?
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
How do you convert 208 volt amps to 480 volt amps?
Add another leg of 120 to a three pole breaker.
What is the amps of a 7.5 hp 480 volt 3 phase?
88 amps
What is VAR?
Volt-Ampere Reactive. It is the reactive component of power when the Power Factor is less than unity (1.0). It is usually measured in KVAR - 1000's of VAR.
What is 70 kVA?

What is the electrical term VAR?
Seeing as how this question is under Home Electricity the term VAR stands for Volt Amps Reactance.See related links belowVAR is a term for computer distribution business. Which stands for Value Added Retailer.
