A way to transmit electricity over a single wire: no zero
Hello! There is such a store, Chip and Dip, where electronic components are sold, and where smart guys with golden hands who understand everything about them gather. About a week ago, I drove there for cable lugs and while standing in line overheard an argument between two schoolchildren, one of which "rubbed" a friend that electricity can be transmitted through one wire, without zero, and the lamp will burn.
I am a builder, not an electrician, but I decided to intervene in the dispute and bring the boy to clean water. But he was put to shame and knocked out by the iron logic of a knowledgeable boy.
It turns out that the guy is right, and electricity can indeed be sent over one wire., without "return". To do this, it is necessary to assemble a generator that will increase the frequency of the transmitted current from 50 Hz to several hundred kilohertz.
Second nuance
, which a schoolboy told me, - the length of the cable should be large enough, at least 3-4 meters. The photo below shows a 12 watt LED light bulb powered by a high-frequency current generator with only one wire.The main disadvantage of this idea is that at a high frequency, the conductor (even isolated) will be an antenna, which means that some of the energy will go into the air. There is an obvious loss of expensive electricity today.
As you understand, if the length of the wire is 100-150 meters, the losses will be even more colossal, therefore, at this stage of the development of science, nowhere from our usual 50 Hz and phase-zero (plus-minus) we do not leave.
But respect to the student for the idea and understanding of the processes!
