What does a longer line represent in the symbol of an electric cell?a)...
- In the symbol of an electric cell, a longer line represents the positive terminal. This terminal is where the electric current flows out of the cell. Just like a plus sign (+) means addition, the longer line in the symbol of an electric cell shows the positive side where electricity comes out.

The Symbol of an Electric Cell
In the representation of an electric cell, the lengths of the lines play a crucial role in identifying the terminals.
Understanding the Lines
- Longer Line: Represents the positive terminal (anode).
- Shorter Line: Represents the negative terminal (cathode).
Why the Longer Line is Positive
- Conventional Current Flow: In electrical circuits, conventional current is defined as flowing from the positive terminal to the negative terminal. This is why the longer line is designated as positive.
- Symbol Standards: These conventions have been standardized in electrical diagrams to ensure consistency and clarity. The longer line helps users quickly identify which terminal is which.
Importance in Circuits
- Correct Connections: Understanding which terminal is positive is critical for connecting cells correctly in series or parallel configurations.
- Safety: Misidentifying the terminals can lead to short circuits or damage to electrical components.
Conclusion
In summary, the longer line in the symbol of an electric cell indicates the positive terminal, while the shorter line indicates the negative terminal. This distinction is vital for understanding how electrical circuits function and ensuring safe and effective use of electrical components.
