Hello. I have a question.

What is the role of the neutral conductor N in electricity and why is no current flowing through the neutral conductor, despite a working receiver connected to the socket?

As common sense, the current should flow, because then the current flows along the line L conductor through the receiver and should return (flow away) through the neutral conductor N.

Please give me a specific answer.

Who said it wasn't flowing? Where does this statement come from?
In alternating current, there is no way in and out, because it happens alternately.

Exactly not. After connecting the receiver to the socket, when I check the current, there is no current at the neutral wire terminal.

How do you check?

Draw a diagram.

Because I understand that the connected device is working during the measurement.

Just out of curiosity, how do you check this current? Ammeter or "sampler"?

I check with a "test tube" while the receiver is turned on.

The test tube does not check the current, but the presence of voltage. There is still a lot of learning ahead of my friend.
I suggest starting with some elementary basics, including definitions.

But despite this, when I touch this neutral wire, the current does not kick. Then how can you check it, buddy?

Ammeter (but read the instruction manual and safety precautions first).

To safely start practicing, you need to know the theory.

You can't check something without knowing what works.

A colleague has no idea what voltage is, what is current.
What causes the current to flow. There are no elementary foundations here.

The current is measured with an ammeter.
The voltage is measured with a voltmeter.

Okay with an ammeter, but if there is voltage on the neutral, why can't it be seen and why doesn't it kick when touched?

Eh. A colleague continues his ...

Please give a definition of the voltage and explain it in your own words.
There must be no voltage on the cable.
The voltage between the neutral conductor and the ground is 0 V, therefore it is called the neutral conductor.

So all the current from the neutral wire goes to the ground and therefore is not on it anyway?

And so, in the will of accuracy, we measure the current with the ammeter, not the friend's current.

Current is not voltage ...

The voltage is the DIFFERENCE of potentials between two points.

If there is no voltage, no current will flow.

The circuit must be closed for the current to flow.

The voltage between the phase conductor and earth is 230 V (in Poland), while the voltage between the neutral conductor and earth is 0 V.

What does that mean exactly? Because I do not understand.

I think the same. I close the topic as worthless.

Topic summary

The discussion revolves around the role of the neutral conductor (N) in electrical systems, particularly in alternating current (AC) circuits. The main question raised is why no current flows through the neutral conductor when a receiver is connected. Participants clarify that the neutral conductor is designed to maintain a voltage of 0 V relative to ground, which means that under normal operating conditions, there should be no current flowing through it if the circuit is balanced. The conversation highlights the importance of understanding the difference between voltage and current, emphasizing that current requires a closed circuit and a potential difference to flow. Misunderstandings about measuring current and voltage using devices like ammeters and test tubes are also addressed, with suggestions for proper measurement techniques and safety precautions.
