VA or volt-amps is also volts times amps, the concept however has been extended to AC power. For DC current:
VA = Watts (DC current). In AC if the volts and amps are in phase (for example at a resistive load) then the equation is also:
VA=Watts (resistive load)
where V is the RMS voltage and A is the RMS amperage.

What is difference between KV and KVA for transmission line?
KV, kilovolts, or kilojoules per coulomb is not the same thing as KVA, kilovoltamperes, or kilojoules per second, and no direct comparison exists. Please restate the question.
What is the difference between 1watt 1kilowatt 1megawatt?
1 mega watt is equal to 1 million watt or 1000000 watt.
How does kvar work?
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
How do you compute ampere if the given is kvA kW power factor and voltage?
Some confusion hereKW and KVA are units of power. The ampere is a unit of current. If you divide power by the voltage involved, you can determine the current involved, in amps. Power (watts) = volts x ampsA volt-amp is a watt. (A volt times an amp is a watt.)I=(KVA*1000)/(1.732*V) (Three Phase)AMP=KW/1000*V*PF--------------------------------------------------------------------------------------------------------------KW or KVA can be converted to one another but you cannot convert them to amps. You can compute amps by using this formula,KW = I x V x 1.732 x P.F/1000 (Three phase)KVA = I x V x 1.732/1000 (Three phase)
What is the difference between a watt and sunlight?
Welll, it's actually a lot like the difference between a mile-per-hour and cars,or between an inch and people.-- "Watt" is a unit of measure that describes the rate at which energy is used,or produced, or moved from one place to another.-- "Sunlight" is a small portion of the stupendous amount of energy that the sunproduces and pours out in every direction at a humongous rate.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
What does the difference between 60-watt and a 100-watt light bulb describe?
power difference
What difference between RF power output watt and electrical power output watt?
The difference is in the output frequency.
How do you find kva?
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
What it is the difference between 100 watts and 75 watt light bulb?
The main difference between a 100-watt and a 75-watt light bulb is the amount of light output they produce. A 100-watt bulb will be brighter and consume more energy compared to a 75-watt bulb. The 100-watt bulb may also generate more heat than the 75-watt bulb.
What is the difference between 35 watt and 50 watt h.i.d. lights?
The main difference between 35 watt and 50 watt HID lights is the power consumption and light output. A 50 watt HID light will consume more power and produce brighter light compared to a 35 watt HID light. The choice between the two would depend on the specific lighting needs and preferences.
What does difference between Watt and Volt ampare?
No difference in case of DC. In case of AC Watt refers to Power which includes the factor of power factor. VA does not include power factor.
What is difference between KV and KVA for transmission line?
KV, kilovolts, or kilojoules per coulomb is not the same thing as KVA, kilovoltamperes, or kilojoules per second, and no direct comparison exists. Please restate the question.
How do you measure volts in kva rating?
KVA means kilo volt amps or kilo Watts. A watt = 1 volt X 1 Amp. Kilo is shorthand for 1000. A watt is a measure of power, which is voltage x amps. Therefore it is not possible to relate voltage to KVA without additional information. Formula wise the above is correct but if you really need the voltage, it can be measured with a volt meter or VOM by putting the test leads across the output terminals of the KVA device.
What is the difference in cooking times between 1100 watt and 700 watt microwaves?
In general, a 1100 watt microwave will cook food faster than a 700 watt microwave. The cooking time difference will vary depending on the specific dish being prepared, but as a guideline, you can expect the 1100 watt microwave to cook roughly 50% faster than the 700 watt microwave.
How many kva equal to 1 mega watt?
KVA is a rating for complex power (real + reactive power): KVA = KVAR + KW Also, there is 1000KVA in 1MVA, so there's at least 1000KVA in 1MW, but if the reactive power load is very high, there may be substantially more KVA.
How many kVA equal kvar?
For normal power factors (pf=80%), you have 0.8 kW for every kva. In general however, kW = pf x kVA. Where pf is the power factor, it is the cosine of the angular difference between the voltage and the current of a circuit in alternating current circuits.
