So I know that the neutral wire is the 'return wire'. But why does my textbook say that it has the potential to have the same amount of electricity as the live wire (if the wiring is faulty)? But essentially, if the wiring is not faulty it is technically safe to touch it, it has 0 volts.Could someone explain this to me?
The electricity supply mains has three wires. They are called Live, Neutral and Earth The Live wire is connected directly to the generators of the electricity supply company. NEVER touch this wire, it carries 230 Volts and can kill you!! The Neutral wire returns the electricity to the generator after it has passed through the appliance, to complete the circuit. The Neutral wire is at approximately zero volts but you must NEVER touch this wire either!! If the wiring is faulty it may be carrying the same electricity as the Live wire. The Earth wire usually carries no electricity, it is there as a safety device. If something in the appliance goes wrong, or it is wired incorrectly, then the Earth wire may be carrying the same electricity as the Live wire. To be completely safe, NEVER touch this wire either!!
In the absence of faults, the neutral should be safe. It is normally connected to ground at the supply entry board or at the substation/transformer. In the event that a neutral wire becomes disconnected between an appliance and the supply entry board, it will be at the same potential as the live wire.
a million. whilst that is working regularly, Voltage could be present for the time of stay and independent twine. cutting-edge could flow from stay to independent twine. 2. whilst there's a fault, The voltage would be present interior the stay twine and since the circuit isn't closed, No cutting-edge could be flowing. 3. No that is no longer ultimate. yet at times, the earth twine could be transmitted to the sub station the place in its joined with the independent. 4. green 5. The Casing could be linked to earth. for this reason the independent is shorted with earth.
