ww lines to indicate how you will connect their terminals with wires to make a battery of four cells.
Answer:
In order to make battery, the positive terminal (+) of one cell should be connected to the (-) terminal of another cell and so on.
Question 4.
The bulb in the circuit shown in figure does not glow. Can you identify the problem? Make necessary changes in the circuit to make the bulb glow.
Answer:
The positive terminal (+) of one cell should always be connected to negative terminal (-) of another cell.
But in case of above circuit both the positive terminals are connected to each other. This is the reason battery is not able to generate electricity.
Therefore the change which should be made to the circuit will be that the positive terminal (+) should be connected to negative terminal (-) of the cell and vice-versa.
