To calculate PF of a machine you need to identify its watts and volt-amps. Power Factor = Real Power (in watts) / Apparent Power (in volt-amps) Let’s calculate the PF of an inverter I have in my house. Luminous NXG 1400 rated with 900 VA while it can handle a load maximum of ...
AC Output:Calculate the totalstarting and running wattageof all the appliances you want to operate simultaneously in watts or kilowatts. Make sure the AC output of the generator exceeds that total by at least 10% Electricity Consumption:Once you’ve determined which devices and appliances you want...
Here, we will define power factor; differentiate between good, poor, and bad power factor; jump deeper into what causes and how to correct poor power factor; and introduce how to calculate power factor, reactive power, apparent power, and capacitance when faced with a power factor correc...
How to Calculate Energy Consumption of Appliances. Power is the rate at which a device uses energy. So for instance an air conditioning unit, shower or kitchen range/cooker uses electrical energy much faster than a light bulb. Power is normally written on a label or embossed into the plastic...
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...
To calculate the lighting load, we use this formula: Watts = Volts * Amps (orW=VAin short). In most cases, you’ll get two of these three elements. For example: If your household circuits have a 240V capacity and can allow up to 20A of electricity at any given time, then your watta...

You can then see how to calculate exactly how much electricity your household appliances use, so you know which items are guzzling the most juice (and which ones are the best targets for savings). You'll also learn exactly how to read your electric meter, if you like. (Find that on any...
