Direction: Q.31 to Q.35

A single cell provides a feeble current. In order to get a higher current in a circuit, we often use a combination of cells. A combination of cells is called a battery. Cells can be joined in series, parallel or in a mixed way.

Two cells are said to be connected in series when negative terminal of one cell is connected to positive terminal of the other cell and so on. Two cells are said to be connected in parallel, if positive terminal of each cell is connected to one point and negative terminal of each cell connected to the other point. In mixed grouping of cells, a certains number of identical cells are joined in series, and all such rows are then connected in parallel with each other.

Read the above passage carefully and give the answer of the following questions.

To draw the maximum current from a combination of cells, how should the cells be grouped?

A) Parallel

B) Series

C) Mixed grouping

D) Depends upon the relative values of internal and external resistances
