How do batteries in a series work?

Question

Ok, I get the basics of how a battery works. A chemical reaction creates electrons which are carried from the negative end of one battery through the appliance and back to the positive end which I guess neutralizes the electron. Ok, now, in a flashlight or other appliance where the batteries are in series, how do the electrons move from one battery through the positive ends of the other batteries and not neutralize. How do the electrons go through positive ends of batteries and are still able to power the appliance?

Thank you in advance

Answer 1

They are like this in an appliance:

Appliance -Battery+ to -Battery+ to -Battery+ to Appliance.  If each battery is 1.5 volts you have three of them, so the appliance gets 4.5 volts to run on.

So the electrons go from the - terminal of the first battery through the appliance and arrive back on the + terminal of the third battery.

They eventually do neutralize, that is when the battery is dead.

The appliance will not use all the electrons the batteries have immediately, it uses them gradually.
