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 calculate the ac resistance of the dynamo and take the load as equal to internal resistance of the generator (max power theorem.) Will this work...I'm not too sure what I'm doing on this one. Thanks.
