How many amps does a 1.5 volt AAA battery produce?
I have to figure out why three AAA batteries power a motor smaller than a 10 watt solar panel can not. The 10 watt panel produces 21 volts, but I can not figure out how many amps it produces.
One thing you have to consider almost any source of energy is the source impedance. If you really load the circuit significantly reduced tension. 21V 10W panel can produce without charge but I bet it decreased to almost zero when connected to the engine.
