Question
For 30 years I have been building Tesla Coils with the secondary attached to
the inside turn of the primary. Never tryed connecting the secondary to
ground until I heard about it here. I have built some Van DeGraffs and know
that the cabnet that houses the motor and drive roller is metal and charges
with a charge equal and opposite to the sphere. The TC secondary attached to
ground acts like the cabnet of the Van DeGraff and also acts like half of the
capacitor in the secondary LC circuit while the toroid is the other half of
the capacitor in the secondary circuit. I have not tried this but it seems
to me that if you were to build a TC with a metal cabnet for the power supply
and connect the lower end of the secondary to the metal cabnet and not to
earth ground and not to the primary it would serve the same purpose and works
on the same principle. Probably a piece of sheet metal on the floor under
the tesla coil would work and maybe better because the metal would build up a
better charge than ground. The metal cabnet or metal plate on the floor
would have to be capable of holding a charge equal to the toroid. Has anyone
tryed a metal cabnet or metal plate?
