Alternating Current, live and neutral wires

[QUOTE="Integrand, post: 5613495, member: 402037"] You need to revise the concept of voltage. Saying that a single wire supplies 230V is incorrect. Ditto with the neutral wire at 0V: 0V with respect to what? (Thinking of earth?) How does this apply to two-wire systems? Saying that a point in a circuit is at such and such a voltage is only acceptable when the reference is understood. I am not a teacher, but I think that in a teaching context every opportunity should be taken early on to establish that voltages are differences. So, a voltage at a point or through a component is nonsense, but a voltage across a component is meaningful. I would not speak of the neutral wire "returning the electricity to the generator", that is wrong in several ways. Avoid using the word "electricity" to refer to anything but the general phenomenon. When referring to any measurable phenomenon like voltage, current, or power, use those words. The descriptions are indeed inconsistent. This is because the fact you assert is not true. Speaking of a return wire in a two-wire ac system is incorrect. Are you aware that the voltage in these systems is also time-varying? [/QUOTE]
