vacuum spark gap over unity?

12v halogen lamp filament is broken...but it lights up with 2kv....WHY?[/color][/font][/size]

becuase the voltage is high enough to make electrons jump from one end of the broken filament to the other closing the circuit.

the halogen gas deposits vaporized metal back onto the filament where it normally would condens on the glass envelope blackening the glass.
i don't think it will burn forever the metal still vaporizes where the spark leaves and hit the filament so the filament slowly melts away.

can u explain why unbroken 12v filament did not light up....?

Hi dreamyear,

what you need to do is connect an AC amp meter to the 230vac side (primary of 1st MOT) to see if there is a difference in current when lighting 2 bulbs (one with broken filament) compared to lighting one bulb.

If the current is the same in both cases then you have something but if the current increases when 2 bulbs are lit compared to one bulb lit then it sounds normal

Thanks for sharing

Hi
same as in a flyswatter  if output contacts are shorted  nothing happens  but if left open  and connected to a normally open relay contacts   produced spark....  just like peter linderman plasma arc mod ( from my understanding)
the busted lamps filaments are broken   to produce light
