The generator emits alternating current. There is actually only one line connected between the generator and the user (the user's live wire and the other line from the generator are both grounded so the charges can flow) . If the electrical appliance is not turned on, there will be no current on the neutral line.
If one end of the generator is not grounded, it will not be able to produce electricity (charge will not flow) and people will certainly not be electrocuted.
h3>Power production for motorcycles coil, separate wires No distinction between neutral and live wires? What are these three yellow lines for? What is the function of the two wires at the contact level?
Nobel said it very well and exhaustively.
In the picture above, whatever wire you connect to ground is the neutral wire. The remaining chain is the live wire. Remove onlyt the live wire, transmit it very far and connect it to your voltage (current) meter. The other terminal of the meter is grounded, which is the neutral wire. This is essentially how power plants provide electricity. But it's actually much more complicated than that. This is actually three-phase electricity. Three live wires are transmitted. The voltage between any wire and the neutral wire is 220, and the voltage between any two wires is 380. This is the actual process, of course, I haven't taken into account the increase and decrease voltage during transmission.
Also, you mentioned the pen testing issue. According to my explanation above, testing electricity with a test pen involves forming a circuit between the wire to be tested, the test pen, the human body and the ground. If this wire is the live wire, there will be current in the middle and the test pen will light up. If this wire is the neutral wire, that isire the ground wire, if you reconnect it there will be no power. between.
As there is a large resistance in the middle of the test pen, people will not be electrocuted during the electrical test. If the test pen is a light bulb and the resistance is not large, it will electrocute people. . This is why people can be electrocuted if the switch is not connected to the live wire and disconnected.
The wires coming out of the magneto (generator) coil of the motorcycle are divided into live wires and neutral wires (i.e. power wires and ground wires). If there are three yellow lines in the magneto output line, it must be a three-phase magneto. These three lines are the output lines of the lighting charging coil. They must be connected to the rectifier and connected to the other three lines of the. same colour. The two "contacts" you mentioned are the wires of thetrigger coil. I don't know if these are the trigger coil wires. Those equipped with three-phase magnetos usually have DC ignition. trigger coil. One is the trigger coil feed wire, usually one. These are ground wires, both of which must be connected to the igniter to provide the ignition signal from the igniter.
