ELECTRONIC QUESTION I have a hand crank generator that is 12V DC I have it connected to a 10 Ohm 100 Watt resistor for load. Ohms law says this should be close to 15 Watts of power. I have a rotation sensor on the crank, I need to figure out how much power is generated per single revolution. The catch is the kids will vary in crank speed. Do I need to calculate the power based on time per input pulse? So if it is 15 W/h generation at 1 full crank per sec. How would I go about calculating power per crank/time.? One thought, use 1 sec as base. If crank is faster than one pulse per sec I would multiply the 15 Watts by the percentage increase. And for a crank pulse that is slower than 1 second, I would remove from the 15 Watts as a variant of the percentage difference in speed. Does this sound correct guys? I was up at 3AM and my brain is fighting me on this one haha Thanks!
