The dude might also be advised to put a wattmeter on the mains input and measure the power input more or less accurately.
The law of conservation of energy again holds. Methods of checking such "phenomena" can be found in the laboratory work No.3 of the first semester of the electrical engineering course.
I should add that the arc has a non-linear c/a characteristic, so the measurements and calculations given are fundamentally incorrect.

i.e. use a high quality direct current source. Only with a high quality DC current (constant in both magnitude and direction) is it possible to accurately measure the power consumption of the system. What to use as electrodes in this case is not quite clear. Platinum? Carbon?
The question also arises: what does water have to do with high voltages at all? Can this effect be possible without water - in a gas environment, although it is more difficult to measure the amount of energy released there. One could probably try an experiment with an arc burning in a gas discharge lamp - fluorescent, mercury, neon, etc.
Man, there's a long-known army-student water boiling machine - two razor blades are tied together with a string, with two matches put between them so that the iron pieces don't touch. A wire is attached to each blade, then plugged into a socket. A glass of water boils in 10 seconds.
I remember one of these. But it's 220 volts. This one's over 2kV.

So the question is this. Is the amount of thermal energy emitted by the arc higher than the amount of electrical energy used to maintain the arc. In terms of school and university physics, they are equal, but .... if you think back to Tesla, e.g. ....

I once used a loop and stick to make a three-phase flow heater in a shop heating system of 30 kva the size of a blueprint tube. It was used to maintain the system during interruptions in the heat supply from the boiler house.
She's a tripwire. The main thing is not to make the gap too small, so that the heating does not go into electrolysis.

Don't remember him, haven't seen much)))
In all seriousness, what is this about?
About that.
