Question

What is the neutral line?

Answer 1

The neutral line in an electrical system is a conductor that carries current away from the load and provides a return path to the power source. It is typically at ground potential, meaning it is connected to the earth ground. In a three-phase system, the neutral line helps balance the load across the phases, reducing the risk of overload and providing stability. In single-phase systems, the neutral is essential for completing the circuit and ensuring the proper operation of appliances and devices.

Answer 2

The **neutral line** in electrical systems serves as the return path for current back to the power source. It is connected to the ground (earth) at the main electrical panel, which helps stabilize the voltage and provides a reference point for the electrical system.

In a standard AC power system, electrical power is typically delivered via three lines:

1. **Live (or hot) line**: Carries the current to the load (e.g., an appliance or light).
2. **Neutral line**: Carries the current back from the load to the source.
3. **Ground line**: Provides a safety path to prevent electrical shocks in case of a fault.

The neutral line allows current to flow safely in a balanced electrical circuit. It typically carries little or no voltage relative to the ground, but if there's an imbalance in the circuit, the neutral can carry current to maintain the flow.

In three-phase systems, the neutral also balances the voltages between phases.
