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.

∙ 14y agoWatts is the product of amps times volts. W = A X V. Electricially put W=IxE where w= watts, I= amps, E= volts
watts = unit of power
amps or ampere = unit of electric current
volts = unit of voltage supplied

∙ 13y agoVolt-Amp is apparent power, in direct current Volt x Amps = power with unit of Watt. For Alternate Current Volt-Amp is generally different from real power because the power supply in wave form and might be out of phase and portion of energy is not usable. Volt-Amp is always higher or equal to real power in AC.

∙ 12y agonormally real power is in terms of watt, and apparent power is in terms of VA. what we are using is real power it means watt. but in generator we have both real power and reactive power(unused power which flows in the same tr. line)
to measure the power in terms of watt use watt meter. then convert the watt into VA by including pf...

∙ 11y agoYou cannot directly convert volt amperes to watts, because they measure different quantities (apparent power and true power). However, if you know the apparent power and the power factor of a load, then you can find its true power (in watts) by using the following equation: true power = apparent power x 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.
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 is the difference between power and watt?
Power is a quantity, and the watt is its unit of measurement.
What difference between RF power output watt and electrical power output watt?
The difference is in the output frequency.
What is the difference in cooking times between 1100 watt and 700 watt microwaves?
3minutes
What is the difference between an amp and a watt?
The relationship is, a watt is the product of amps x volts.
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 is the difference between 35 watt and 50 watt h.i.d. lights?
15W, asuming that you are talking about the same type of lamp.
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.
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.
What it is the difference between 100 watts and 75 watt light bulb?
25 watts?
