"Power is volts times amps. period. Given impedance, and watts, it is a simple ohms law calculation to determine voltage and current."Uh, no. Power is volts times amps ONLY if the phase angle is zero......as in DC circuits.
It gets a little more complicated in AC circuits.
You're on the right track though. :)The AP testing scenario is a good one because it measures power at various phase angles and dynamic conditions.
