Neutral Voltage Question

fiftyhertz
Hi all, 


Hoping someone can help with this, as it bothering me that I dont know this. 


This is quite tricky to explain without an image. Essentially, if we have a circuit supplying one luminaire. The line conductor has a voltage of 230v from earth potential supplying the light. To complete the circuit, on the return leg a neutral is required (<50v from earth potential). Where is the point where the neutral is no longer at mains voltage, is it at the neural terminals? 


Is it a case of the luminaire will "use up" the supplied mains voltage? 


Any assistance is appreciated. 


Thanks

    ... if you could cut the load in half and stick a meter half way along - and with an old fashioned bar type electric heater maybe you could, that point would be equally far from the original L and N, and so at 120 V to earth or so. 




    Sounds like a good old-fashioned potentiometer!
