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.
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
The difference is in the output frequency.
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
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.
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.
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.
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.
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.
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.
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.
