So does the strength of the pressure positively relate to the number of electrons and positive charges on both sides?When a positive charge is separated from a negative charge there is a force of attraction between the two charges very much like gravity.
This is the electrical pressure or potential.
I have read the page, and it's helpful. However, there's one place I don't quite understand. Say an non-rechargeable battery doesn't store electricity, rather it produce electricity by chemical reaction. If the battery is rated at 12V 2.4amp-hour and the radio only need 1.2 amp, inside the battery which condition is more true:If you look at the top of the Chat page, there is an article called, "Ohm's Law for noobies". It really breaks this down to basics.
No electrons are being produced or stored. The chemical reaction in the battery separates charge by the physical movement of +/- ions (atoms). The charge separation creates a electric field between the cell electrodes that slowly moves (not produces or creates) the free electrons in the conductors of the current to the load and back.I have read the page, and it's helpful.

1.) electrons being produced at the rate of the load required
2.) electrons being produced at a constant rate unaffected by the load require, and electrons will be stored somewhere in the battery before being send to the positive side
Huh?Now, suppose you went to the store and bought (2) five gallon containers for compressed air. You take them home and use a compressor to add air until each of them has 5 psi. Then connect them in series. You will measure 10 psi because one volume of air is pushing on the other volume of air. Same thing for batteries.
I know the feeling well!You're right. Must have had my head up my...
And that actually concerns me a tad, as well!Anyway, it seems to have convinced the OP, even if it was a bad example.
This pneumatic analogy is somewhat misleading, containers filled with air have no inherent polarity, so connecting them in series would not increase the pressure.Now, suppose you went to the store and bought (2) five gallon containers for compressed air.
