Re: An inexpensive X-ray machine

Hello, here I go again; I thought that an Oudin Coil the primary voltage was
additive to the total secondary voltage. Ie secondary connected to the top
of primary and bottom grounded as shown in the second and third website but
not in the first web site. The first site (www.physics...) looks more like a
tesla coil grounded. maybe all my tc's were Oudins after all??
