understanding the basics, whatâs more important volts or amps when charging a battery from a generator?
I am getting confused my high school electronics is being tested, i passed by the way ;) . I want to make my own electricity from solar and wind to charge up some batteries. What voltage must my system produce to charge two 12 volt batteries? In my wind generator I envisaged using a stepper motor, with this it is possible to use a voltage doubler circuit. The article I read on reuk.co.uk stated that if you doubled the volts you halved the amps.
So to get to the point, which is more important volts or amps? And why?. (please)
