Why You Should Never Connect the Two Terminals of an Electric Cell Directly
When you directly connect the positive and negative terminals of an electric cell, known as short-circuiting, several important consequences occur. Here’s why option 'B' is the correct answer:
Depletion of the Cell
- Connecting the terminals directly allows a large current to flow without any resistance.
- This rapid flow of current depletes the chemical energy stored in the cell quickly.
- As a result, the cell will run out of energy faster than normal use.
Heat Generation
- The direct connection generates excessive heat due to the high current.
- This heat can damage the cell, potentially causing it to leak or even rupture.
Lack of Control
- In normal circuits, resistors or devices regulate the current and voltage.
- Without these components, the current becomes uncontrolled, leading to inefficiency.
Potential Damage to Devices
- If connected to a device, the sudden surge of current can damage sensitive electronics.
- This can lead to malfunction or complete failure of the device.
Conclusion
- While a direct connection may seem harmless, it can rapidly deplete the cell and lead to irreversible damage.
- Always use batteries and cells as intended, ensuring proper connections through appropriate circuits.

Connecting the two terminals of an electric cell directly without a proper circuit can cause the chemicals inside the cell to be used up rapidly, leading to the cell's quick depletion. This is because a direct connection creates a short circuit, which is harmful to the cell's longevity.
