These condensers consisted of plates in oil that were movable. The condensers were of a special design, small with high insulation. The discharge tips usually preferably metal balls under one inch in diameter, though Tesla used various forms of dischargers. A spark gap is placed in parallel to the Ruhmkorff coil before the condensers. The Ruhmkorff coil, being fed from a main source, is wired to condensers (now called capacitors) on both ends in series. The setup can be duplicated by a Ruhmkorff coil, two condensers, and a second, specially constructed, disruptive coil. These early coils would use the 'disruptive' action of a spark gap in their operation.
In the majority of Tesla's experiments, he used machinery of his own design to produce the Tesla effect. 34-35)įollowing the initial research of voltage and frequency by William Crookes, Tesla developed a series of coils that produced high- voltage, high-frequency currents. 6 B & S wire, and the whole combination immersed in a vessel containing linseed or mineral oil. Into this is slipped a primary consisting of eight to ten turns of No.
The American Electrician gives a description of one wherein a glass battery jar, six inches by eight inches, is wound with 60 to 80 turns of No.
