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.
Watts 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
Volt-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.
normally 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...
You 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
kva is an apperent power which is ac,depends on phaseangle eg-e=25cos wt.while watt is a true power which is dc eg-p=vi
The formula you are looking for is; Watts = Amps x Volts. So in your case
VA is Watts
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.
1 mega watt is equal to 1 million watt or 1000000 watt.
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
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)
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.
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
power difference
Power is a quantity, and the watt is its unit of measurement.
The difference is in the output frequency.
3minutes
The relationship is, a watt is the product of amps x volts.
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
15W, asuming that you are talking about the same type of lamp.
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.
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.
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.
