So my question is as follows. We use P=(V^2)/R for our uses. This is derived from Watt's Law, P=VI and a variation of Ohm's Law I=V/R, so we can replace the unknown I and solve for P. So I guess it would be more correctly called Watt's (or The Power) Law, but we still use Ohm's Law to come up with the variation that we use. I guess those calculators should be called Ohm's/Watt's Law Calculators. Would this satisfy everyone?
