Question

Which of the following should be placed in box 'X' to make the bulb glow more brightly?

• A. Bulb
• B. Cell
• C. Fuse
• D. Switch

Answer 1

The correct option is C Cell

1. A cell converts stored chemical energy into electrical energy.
2. It makes the current flow from the positive terminal round to the negative one via an external circuit.
3. An additional cell in the circuit will provide more electrical energy, which will make the bulb glow more brightly.

The additional battery should be connected to the circuit like the above figure, i.e., the positive terminal of one battery should be connected with the negative terminal of another battery.
