In this video from LearnElectrics, we will take a very gentle look at this thing called power factor, and show you how we use Watts and volt-amperes to help us look at how efficient a system is. Starting at a nice easy level, we look at what the different terms mean and how they work together in an electrical installation.
There are always lots of questions about power factor and some of them have included things like …
How can I calculate power factor and Watts?
What is power factor and how does it affect the installation?
And why are VA and Watts different, I always thought that V times A was Watts? And now it isn’t.
But before we start on working out VA and power factor, we will have a look at some basics on the subject of waveforms and resistive and reactive circuits. All good stuff, helpful, interesting, and nice and easy to understand.
