what is power factor in electricity?
In: 362
Really what it is saying is how much energy is your system using efficiently. I really describe it as this. Imagine you are pushing a heavy object to slide it straight across the room . The most efficient way to do that is you try to push it from directly behind it. In this way your pushing (voltage) and it moving across the floor( current) is completely in phase. So PF =1.
Now the above is great in a perfect world. But now let’s say let’s say the heavy object(maybe think fridge or stove), and you can’t get straight behind it so along with pushing it back you also push it towards the left. Now your pushing in two directions but really only care about pushing it straight back. You are still expending energy to push it to the left though. In this case you are spending desired energy to push it back but also in effect using energy to push it to the left. PF is the measure of how efficient you are pushing that object.
