Series Cells
Cells are basically electrical elements. Cells employ chemical reaction to produce electrical potential.
Series cells are produced by individual cells connected together. It is done by connecting the positive terminal of a battery to the negative terminal of another.
Series cells are usually used by certain equipments which need higher voltages. In order to produce higher voltages we connect the cells in series.
The figure shows two 1.2 volt cells connected in series. Here, the opposite terminals are connected to each other. As they are connected in series the net voltage produced by the combination will be
Thus, as two 1.2 volt cells are connected in series we get a cell whose net voltage is 2.4 volts. Thus, a series combination of cells can produce higher voltages.
The net internal resistance of the series cell is given by
rnet = r1 + r2… rn
where r is the internal resistance of the individual cells
Parallel Cells
When positive terminals of every cell are connected together and negative cells are connected together in a cell, then we call the cells as parallel cells. These cells are usually used by devices which need to produce higher current. The figure shows parallel connected batteries.
Here the total current delivered by the cell is equal to sum of current supplied by the individual cells.
The net internal resistance of the cell is given by
Here, r is the internal resistance of the individual cells. If the emf of the individual cells is similar, then emf of the battery which is connected by n cells in parallel will be equal to the emf of each individual cell.
