Accumulator or Battery
Battery or storage battery is an electrical battery where in it to take place electrochemistry process which reversible (can feed back) with the high efficiency. The concerned electrochemistry process reversible, be in battery can take place chemical distorting process become electric power (evacuation process), conversely from electric power becomes chemistry energy (recharging by the way of regenerate from electrodes) what used, that is by overcoming electric current in direction (polarity) which at the opposite in battery. Every this battery consisted of two kinds of different electrode, that is positive electrode and negativity electrode plunged in a chemistry solubility.
Electrical Current
It is flows it electron in continue at conductor as result of difference of number of electron at some locations which number of the unegual electrons. Set of electric current is Ampere. 1 current ampere to be the flow electron 628x1016 or equal to 1 Coloumb per second pass a upper side conductor.
