Want this question answered?
This question is not quite clear but I will try it somehow. The voltage drop between the live and neutral, and live and earth will both be 230v, but the voltage drop between the neutral and earth is almost zero due to the fact that the neutral and earth is basically one conductor split.
you cant live on Jupiter
I think you mean "what is the permissible imbalance between live and neutral current" All current supplied by the live wire should exit via the neutral. Any imbalance leaving via Earth is detected by an earth leakage circuit breaker . They trip at about 30 mA.

All depends on what country you are in, wiring standards and cable type. Industrial cable in the UK is. :- Red = Live Black = Neutral Copper wire = earth. (add Green/Yellow striped sleeve at junctions.) Domestic is:- Brown = Live Blue = neutral Green/yellow stripe = Earth Europe Black = Live Blue = Neutral Brown = Earth
You can measure a small voltage between earth and neutral, even if the neutral is grounded to earth, because the neutral conductor acts as an antenna picking up electromagnetic radiation in the atmosphere. -------------------------- If the above answer were true, the earth conductor would also act as an antenna. But the real answer is, if you read ANY voltage between the neutral and earth, the neutral is broken somewhere between where you are measuring and the panel or not properly bonded in the panel. Call a competent electrician to repair the problem.
There is no such thing as a 'neutral phase'. 'Live' or 'hot' conductors are called 'lines', whereas the neutralconductor is at approximately earth (ground) potential.So, a toaster would be connected between a line and a neutral conductor.
Because there is a potential difference between the live and neutral wires.
the planet uranus doesnt have air yu can breath but earth has air we are able to live there
Live, neutral and earth. The supply is carried on the live and neutral, and the earth normally carries no current, but if there is a fault the earth is there as a safety factor and in some conditions it carries enough current to blow the fuse and make the circuit safe.
Three: Live, Neutral and Earth
Current in a standard house is AC (alternate) so it doesnt matter if the live and neutral are crossed. Should the earth and live be crossed then the earth leakage would trip
