# What is a Neutral Wire?

Basically you know that, in any electrical circuit, two potentials form the circuit and allow the current to flow - phase and neutral. Phase is the conducting wire which carries the current and neutral is the conducting wire which does not carry the current but completes the current path by redirecting it to the source point. So, the neutral wire is used to complete the current flow in the circuit. Without the neutral wire, current will not flow through the load. It is also known as the zero potential point. Basic load is connected to two points – phase (red line) and neutral (black line). The third point is connected to the earth. Practically, the neutral wire is connected to the ground. When the live wire carries the current to the load and the neutral wire receives the current returning from it, the neutral wire must be non-conducting, in which case it will be conductive.
So, to make it non-conductive, the neutral wire is connected to the ground without a neutral point. It cancels the path and makes it non-conductive. (It is worth noting that in practice, non-conducting means low-conducting. If we add phase currents, a small return current always flows through the neutral wire. It is negligible and less harmful compared to the neutral wire. Connected without ground). Neutral is the point where three windings of the transformer meet, we can consider the neutral as star-point of the transformer. It is then distributed to various single points that we use in our daily life. Also, another thing to note is that the neutral wire carries a very small amount of current, the size of the conductor wire may be smaller than the phase wire.
