Hello!
I have a science investigatory project issued by my school. For my (actually our) project, we decided we will make a some sort of concept alternator powered by water collected from rain. Our goal is pretty small, to power up a small 5-volt bulb. Assuming the rotor rotates 2-3 times a second, how many turns will the coil need to attain 5 volts or more?
Edit: I meant magneto by alternator.
Thanks!
