Va how many watts

When you have reactive circuit elements the current can't keep up with the voltage, but lags behind. So in AC, if the volts and amps are not precisely in phase you have to calculate the watts by multiplying the volts times the amps at each moment in time and take the average over time, i. The ratio between the VA i.

When you want to know how much the electricity is costing you, you use watts. When you are specifying equipment loads, fuses, and wiring sizes you use the VA, or the rms voltage and rms amperage. This is because VA considers the peak of both current and voltage, without taking into account if they happen at the same time or not.

How do you find the power factor? The idea is that you multiply the amps times the volts for every increment of time and take the sum and average. The formula to perform the conversion comprises three variables VA, Watts and power factor , which are related in the previous formula.

It is always preferable that you obtain the value of the power factor with the equipment catalogs. You must obtain the VA of the load you want to convert to Watts , for this you can go to the nameplate or catalogs of the equipment s , you can also perform an Internet search with the reference of the equipment s , commonly the power of these electrical devices They come in watts , however there are some inductive loads that have motors and a load assignment in VA.

Find the power factor of the equipment for which you want to convert the power of VA to Watts. The power factor is a bit elusive and difficult to find , however you can search on the Internet or in the catalogs with the references of the equipment or similar. You can also use power factor reference tables. A refrigerator has a power of VA on its nameplate with a power factor of 0. What will be the wattage of the refrigerator?

To know the power in Watts you must multiply VA by 0. A clothes dryer has a power of VA and a power factor of 0. A computer has a power of VA and a power factor of 0. A freezer has a power of VA and a power factor of 0. To convert VA to Watts you must have the power factor. Assuming a power factor of 0. In simple terms, imagine UPS power capacity as the amount of soda in a glass. The actual liquid in the glass represents the real power of the UPS, or the Watts.

This ensures you will get the maximum amount of power for your investment. Interested in more information like this? India Site Map Change Country. Kilowatt to Ton. Watt to Kilowatt.
