What is the function of neutral link in an electric circuit?

Neutral links are small pieces of metal that act as the terminal in a circuit. They may be used in conjunction with one or more fuse holders, which allow the neutral link to sit next to live connections. The voltage at the point of the neutral link is zero, though they do still carry current.

Why does AC current need a neutral?

It is easily demonstrated that the two power wires to any piece of AC equipment can be interchanged without any affect on function. The reason that one of the power wires is named “neutral” is because it is connected directly to the building ground connection at the circuit breaker panel.

Why is fuse connected to live wire and not neutral?

Once the fuse has melted, the circuit is broken and no more current flows through the device. The fuse or circuit breaker must be connected in the live wire side of a domestic circuit to ensure that it keeps high voltage from reaching the user, or surroundings, if a fault develops.

Why fuse is not provided in neutral of AC supply?

Current will flow quite well in this circuit, overheating the wires and either fusing them, or causing a fire. The fuse in the neutral does not blow, because there is no current in the neutral. The only functional place to put a fuse is in the wire that always will carry current: the hot wire.

Why should switch be connected only on the phase wire and never on the neutral wire in an electric circuit?

Human body or any living thing is susceptible to high potential and can get a lethal blow from high potential points. Neutral Is the point tied to earth potential hence no flow of charges. This is the reason why the switches are connected on the phase line to break it to be on the safe side.

What is neutral in single phase?

Neutral is a Zero potential point which do not have any potential. Exactly we can say it as, the perfect ground point is called Neutral point because of each single phase loads needs the current return path. Due to that ground resistance, we cannot get the exact output from the source.
