What purpose do neutrals serve in electric circuits?

• A. They increase voltage in the circuit
• B. They carry current back to the source, completing the circuit
• C. They act as a backup power supply
• D. They reduce interference in electrical signals

Answer: (B)

Neutrals in electric circuits play a crucial role in completing the circuit by carrying current back to the power source. After the current flows through the load—such as a light bulb or an electrical appliance—it returns along the neutral wire to the source, allowing the circuit to function properly. This return path is essential for maintaining a balanced electrical system and ensuring that devices operate effectively and safely. Understanding the importance of neutral wires helps clarify their function in circuit design and electrical safety. Without a neutral, circuits would not have a complete path for electricity to flow, leading to potential hazards and malfunctioning devices. The neutral wire also helps stabilize the voltage levels within the system, allowing for consistent performance of electrical devices.
