You can have a car battery and a motorcycle battery, both of which are 12V, but say the car battery can move more charge than the motorcycle battery. This amounts to the car battery being able to transfer more energy than the motorcycle battery. In saying that the car battery can move more charge, is this the same thing as saying the car battery can output a higher current than the motorcycle battery?
Next, if you place both batteries in circuits with identical resistances, it would seem that by Ohm's law they should output the same current. Is this where internal resistance comes into play? Is it the physical properties of the two batteries that would result in different internal resistances? The car battery, being larger, having more chemical capacity can move more charge or output more current than the motorcycle battery and we describe this in terms of a smaller internal resistance for the car battery than the motorcycle battery. Correct or no?
