What is the function of a neutral conductor in an AC circuit?

• A. Provides power to the load
• B. Acts as a return path for current to complete the circuit
• C. Steps up voltage
• D. Stores electrical energy

Answer: (B)

The neutral conductor in an AC circuit serves as the return path for current to complete the electrical loop. The hot (live) conductor provides the voltage, and current flows through the load from hot to neutral, then back to the source, forming a closed circuit. Without this return path, the load wouldn’t be powered. The neutral is connected to earth ground at the service equipment to establish a reference potential and help safety, but its normal job is simply to carry current back to the source. It does not supply power, we don’t use it to step up voltage, and it doesn’t store energy.
