What is the role of the neutral wire in an electrical circuit
There are three basic electrical lines or wires: the phase wire, the neutral wire, and the ground wire. These are the most important wires in a single-phase or 220 volt system or (110v). But if the phase wire is the one that carries the electric current, what is the role of the neutral wire in electrical circuits? Its symbol and color in electrical connections? In this brief educational article, we will try to answer this question.
What is the role of the neutral wire in an electrical circuit:
The role of the neutral wire is evident in providing a path for the return of the electrical current (electronics) to the source, i.e. the generator.

It is called the neutral because its voltage is zero, which helps in creating an electrical potential difference between it and the phase wire, and thus the current flows from the point of the highest electrical potential to the point of electrical potential, The least and most common color of the neutral electrical wire is blue or black in some cases:

The neutral wire is considered a balance point as it is connected to the ground to avoid generating electrical potential differences, The neutral wire is used to ensure the safe flow of current and reduce the risk of electrical accidents.
