The neutral wire in a domestic electric circuit has the colour.

Correct option is C

• In most countries, including India and many others, the neutral wire in a domestic electric circuit is typically colored black.
• The neutral wire serves as the return path for the current to complete the electrical circuit. It carries the current back to the electrical panel and ultimately to the ground.
• The standard color coding for wires in electrical circuits helps ensure safety and clarity in identification.

• Neutral wire is connected to the ground at the main service panel and is designed to carry current back to the power source.
• It is important to identify the neutral wire correctly to avoid electrical hazards and ensure proper functioning of appliances.
• Grounding and neutral wires are crucial for safety, as they prevent electrical shocks and help in maintaining proper voltage levels in the system.

• Red – Red is generally used for the live (or hot) wire, which carries current from the power source to the electrical device.
• Green  – Green is typically used for the earth (ground) wire, providing safety by directing excess electricity to the ground.
• Yellow  – Yellow (sometimes with green stripes) is used for grounding or earth wires, depending on the country.
