Not sure if the title is clear enough, but basically I've got a practical in a couple of days time and I have to construct an experiment to prove that P=IV by proving that P is greatest when the value of r (internal resistance) is zero and total resistance is equal to R (normal resistance).(adsbygoogle = window.adsbygoogle || []).push({});

I'm quite confused at what this is actually asking me to to do. Any ideas.

thanks
