Hey folks,
I built a generator for fun and I would like to find out how much power it is producing when I use it. I have a way of measuring mechanical power in but I am not quite sure on how to measure electrical power out. I'm thinking I could use some LEDs to create a load (or maybe capacitors?). I can measure voltage with an Arduino but I'm not sure how or if I need to find the current.
Can I find the resistance of the LED's and the rest of the circuit with a multimeter then use P=V^2/R to get power?
Any suggestion, potential circuit layout, or other insight would be helpful.
