<span>Batteries have three parts, an anode (-),
a cathode (+), and the electrolyte. The cathode and anode (the positive
and negative sides at either end of a traditional battery) are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the anode.
When the object is placed between centre of curvature and principal focus of a concave mirror the image formed is beyond C as shown in the figure and it is real, inverted and magnified.
