The power formula states that Volts x Amps = Watts. Watts is like the actual beer in the mug- usable power. But with a reactive load like a motor, the electromagnetic field creats REACTANCE, which is wasted power- the foam head at the top of the mug. But guess what, the power company charges you for the whole "mug"- Wattage AND Reactance. So how can you get your money's worth? That's measured in "Power Factor", which we will discuss next time.
