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 (A) measure electrical current flow, while volt-amps (VA) measure apparent power in an electrical circuit, which is the combination of both real power (measured in watts) and reactive power. Essentially, amps refer to current, while volt-amps refer to total power.
100 watt is equal to how many va?
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
Convert Volt-amps to total amps?
To find your amps, divide your volt amps listed by the voltage you are using (and the device is rated for).Power in watts = Volts X AmpsVolts equals amps X resistance. All of these formulas can be transposed to find the missing element.If something is listed as 360 Volt amps and the voltage used is 120 volts it draws 3amps. So if the same device was used on a 240 volt circuit it would draw 1.5 amps. the power company charges for power (watts) so the volt amps are listed on the device and costs you the same regardless of the voltage used.If the same thing was designed for 12 volts it would draw 30 ampsThe current in amps is equal to the apparent power in volt-amps divided by the voltage in volts:A = VA / V
12 volt 9.6va what does this mean in amps?
9.6va (or watts) divided by 12Volts = 0.8 amps
What does half a volt equal in watts?
You need to know amps to answer this... Amps x Volts=watts
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).
Is it true that volt amps are the same as watts?
No, volt-amps (VA) and watts (W) are not the same. Watts measure real power in an electrical circuit, while volt-amps represent the apparent power, which includes both real power and reactive power.
What is the difference between amps and volt-amps?
Amps (A) measure electrical current flow, while volt-amps (VA) measure apparent power in an electrical circuit, which is the combination of both real power (measured in watts) and reactive power. Essentially, amps refer to current, while volt-amps refer to total power.
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.
100 watt is equal to how many va?
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
What is the difference between watts and volt-amps?
Watts measure real power in an electrical circuit, while volt-amps measure apparent power, which includes both real and reactive power. Watts represent actual energy consumed or produced, while volt-amps account for the total power flowing in a circuit.
What does 20VA mean?
20VA stands for 20 volt-amperes, which is a unit used to measure apparent power in an electrical circuit. It is calculated by multiplying the voltage by the current in an AC circuit. It represents the total power in the circuit, including both real power (watts) and reactive power (volt-amps reactive).
How do you convert 208 volt amps to 480 volt amps?
Add another leg of 120 to a three pole breaker.
How many volt amps in 12 volt battery?
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
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
What is the amps of a 7.5 hp 480 volt 3 phase?
