Question
The positive terminal of a cell is directly joined by a connecting wire to its negative terminal. After some time, when the cell is used in a torch, and the torch is switched on, its bulb ___.
- Lights up
- Does not light up
- Does not light up for sometime
- None of the above
Hint:
If the electrodes are joined together, the resistance of the circuit will be negligible.
The correct answer is: Does not light up
- If the electrodes are joined together, the resistance of the circuit will be negligible leading to high flow of the current within the circuit and the magnitude of the current will be so high that it will damage the connecting wire and there are even chances of damage of the battery.
- So bulb will not light up
