Interchanging Terminals in a Circuit

In a simple circuit consisting of a cell and a bulb, the bulb will not light up again if the negative and positive terminals of the cell are interchanged. This is due to the direction of flow of electric current in the circuit.

Direction of Current Flow
- In a circuit with a cell and a bulb, electric current flows from the negative terminal of the cell to the positive terminal through the circuit.
- The flow of current is determined by the potential difference between the two terminals of the cell.

Effect of Interchanging Terminals
- When the terminals of the cell are interchanged, the potential difference across the circuit is also reversed.
- As a result, the direction of current flow in the circuit is reversed, causing the bulb not to light up.
- The bulb requires current to flow in a specific direction to produce light, and reversing the direction of current flow prevents this from happening.

Conclusion
In conclusion, interchanging the negative and positive terminals of the cell in a circuit will not light up the bulb again due to the reversal of the direction of current flow. It is important to maintain the correct polarity in a circuit to ensure proper functioning of electrical components.
