Does Jacob's ladder require DC or AC voltage? And is there anything in CRT monitors to create it?

Question

Do it yourself

In general, I turned up a couple of three CRT monitors, I want to put them somewhere for business.
There are two options, either Jacob's ladder or electrolysis.

Answer 1

Variable, it is precisely due to this that it “moves” upwards, stepping one step upwards at each half-cycle.
The CRT monitor must also have a horizontal transformer, on the basis of which a step-up transformer can be wound.
