electricity

One day, when I use my electronic dictionary, a warning window came out to remind and warn me the voltage of the battery is not available, not enough for further using.
Then I think, electrons of which atom is being pushed?
Is it that the electrons of the circuit?

[dave]

Huh? What atoms where?

[JaKiri]

English only please.

[Lance]

I think hes talking about his laptop? The battery of his laptop got low?

[QuarkQuarkQuark2001]

How about some electronic appliance, where electrons from that the voltage from the batteries push?

[mossoi]

Does he mean "How do electrons move in a conducter carrying a current?"

in a simple battery a chemical reaction takes place between 2 conducting materials, each material has what`s known as an Electrode Potential, some materials are positive and some are negatively charged due to the nature of their electron count and configuration. when these 2 different materials react they create a flow of current as they try to neutralise each other, we can then use this current to make electrical things work. but when the 2 materials in the battery are worn out and done all the reacting they can, the current flow stops, and so does your electrical item.

I`ve kept this as simple as possible, hope it helps explain it a little though :)

Oh thanks
Now I know there are two electrode inside an electronic appliance.

[YT2095]

Close, but not quite right, there are 2 electrodes in any single battery cell.

the appliance that uses this battery power may have many electrodes or rather conductors (like wire) in it :)
