Thanks for the info. This goes with the way I thought bills are calculated, how many watts you use, am I missing something here? I am familiar with the power wheel, I asked

Besoeker what formula he used because I didn't see how he got his numbers in post #12 with an upside down fraction based off the formulas to find ohms. I used E/I same as V/I in this wheel below.

It is funny, because what is simple to one person can be difficult to another. I don't know what your math sites stated, but it is simple for me to understand the concept that wattage and amperage proportional. When one goes up, the other goes up the same percentage when

**ALL** other factors stay the same, period. Voltage and amperage or inversely proportional. When one goes up, the other goes down the same percentage when

** ALL **other factors stay the same, period. Two very important factors here, "all other factors stay the same", and this is the formula for DC circuits, which I didn't note anyone else mentioning. All of the formulas on the wheel are for DC power. That is fine for AC as well to get to general assumptions.

So, to start you back on the road to confusion, The wattage that a unit uses is a measure of the power that it takes to produce the results. The power that must be delivered to the unit to produce that wattage (or work) is probably not the same as the power at the unit. One major contributor to difference between the power inputted to a unit and the power required to be outputted from the generation is the power factor, which is a product of the phase angle between voltage and amperage. Any phase angle other than 1 causes a loss of usable power at the equipment and must be factored in to any Alternating current application. Confused yet?
