But I know the maximum power will occur when the load resistance is equal to the internal resistance so I guess I could just measure the current flowing in this circuit. I'm just after a single number to act as a conversion factor to kw/h.

Hi, I have a small DC dynamo (with no spec sheet) which i digitally sample to find it's voltage at any given time. I want to display theoretical max power output, how can I calculate this? Can I use P=V^2/R where V is measured. How do I calculate R? I read a wikipedia article which says to...
