Correct option is C
The correct answer is: (c) Black.
In domestic electrical circuits, the neutral wire is typically black in color according to older wiring conventions. It serves as the return path for current back to the power source.
Key Features of Domestic Electric Wiring:
Neutral Wire (Black):
The neutral wire carries the current back to the source after it has passed through the load (e.g., an appliance).
It is an essential part of completing the electrical circuit.
Additional Information:
Other Wires in Domestic Circuits:
Live Wire (Red):
Carries the current from the power source to the appliance.
High potential and should be handled carefully.
Earth Wire (Green or Yellow-Green):
A safety wire that provides a path for leakage currents to prevent electric shocks.
Modern Wiring Standards:
In newer systems, the neutral wire may be blue, as per updated standards (e.g., IEC and national guidelines).
Significance of Wire Colors:
Proper wire color coding is crucial for safety and ease of identification during installation and maintenance.
It helps prevent accidents such as electric shocks and short circuits.
