Well Guido I guess if you try connecting that cct up it'll soon show you there are problems, namely a short circuit around each battery.
Take the right-hand battery for example. Follow the black wire up from the left-hand terminal, and see it change to a red wire. This colour change will not impress the electricity except maybe it'll get a good laugh.
Follow the re-coloured wire down to the left-hand terminal of the middle battery. Notice a red wire leading off that terminal to the right-hand battery - the right terminal of the right-hand battery.
The same is true of each battery in the circuit.
So, each battery is short-circuited, and if you want to try connecting them that way I recommend heavy gloves and safety glasses.
Time for some encouragement.
Don't let this misconception stop you from learning about electricity or electronics. Nobody ever got good at seeing how circuits work without mistakes to make them blush and hide. Certainly not myself.
