Answer 1

Almost all of the batteries at the store, A, AA, AAA, C, D, they all have the same voltage. To get a higher voltage you have to chain them positive end to negative end. That’s why batteries are normally placed in alternating directions in a device.

So 3 AAA batteries gets more voltage, and that is important for some applications.
