What role does a neutral wire play in an electrical circuit?

The neutral wire plays a crucial role in an electrical circuit by providing a return path for current. This is essential for the proper functioning of the circuit, as it allows electrical current to flow back to the source after passing through the load, such as a light bulb or appliance. Typically, the neutral wire is connected to ground at the service panel. This connection helps to stabilize the voltage levels in the system and ensures safety by providing a pathway for excess current to dissipate safely into the ground.

Grounding the neutral wire minimizes the risk of electrical shock and helps protect equipment from surges. By maintaining balance in the electrical system, the neutral wire prevents potential overvoltage situations that can arise if there’s an imbalance between the live and neutral wires.
