Question -

The bulb in the circuit shown in Fig. does not glow. Can you identify the problem? Make necessary changes in the circuit to make the bulb glow.



Answer -

The problem in this circuit is the connection of two cells. Here both the positive terminals of the cells are connected to each other. This must be reversed for any one cell to make the bulb glow i.e., positive terminal of one cell should be connected with the negative terminal of the other.
