Battery
Battery
Cell provides much less electricity as compared to that provided by the electric supply line, for example in the case, a single electric cell which provides only 1.5 V of electricity, whereas electricity from the power station is supplied to our home at very high voltage of 220 V.
Battery:
We know that the higher voltage can be obtained by combining a number of cells in series. So, when the positive terminal one cell is joined with the negative terminal of the other cell, then the cells are said to be joined in series (as shown in the figure given below). So, a battery can be defined as the group of cells joined together in the series, e.g. in a torch, cells are placed one after the other.
But in many devices, cells are not placed one after the other, but the two cells are placed side by side (or parallel to each other) instead of single one.It is also a type of a battery as two or more cells combined with a parallel combination provide longer time for flow of current. For example in a TV mote control.
