Tesla’s patent “Coil for Electromagnets,” #512,340, states that the double series winding, whether as a flat spiral or conventional helix, eliminates self-induction and stores more energy than a single wound coil at resonance.

A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. [2] [3] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.

Jun 6, 2018 · As early as 1893, Tesla already patented a very unique flat spiral coil design, now commonly known as the “bifilar pancake coil”. This coil was wound using two parallel wires, and then connecting the end of one to the beginning of the other wire.

Tesla INTENTIONALY WEAKENS mutual inductance with attached coil, which is exactly the OPPOSITE with apperhension of energy conveyance efficiency by induction in the classic sence and that is the main characteristic of transformer.

Tesla invented the Tesla coil during efforts to develop a "wireless" lighting system, with gas discharge light bulbs that would glow in an oscillating electric field from a high voltage, high frequency power source.

Metal Foil caps are normally the best type to use for MMCs. Metal Film caps are normally not recommended for MMCs unless the primary peak current is well within the capacitor's ability.

Nov 28, 2016 · Tesla Coil. Named for its inventor, Nikola Tesla, a Tesla coil is an electrical resonant transformer circuit capable of producing a potential of millions of volts. The coil is used to produce high-voltage, low-current, high frequency alternating-current electricity.

The energy at the outer lead of the flat spiral coil is that of a unified longitudinal wave where the electrostatic charges have completely rejoined. The energy at the terminal of the flat spiral is a split longitudinal wave with the charges held apart from each other.

Using the schematic below with a 13" single wound coil, 3.5 turns of RG59 coax as the primary, two .054µF capacitors, a magnetically quenched static spark gap, and 15KV 60mA NST, I set up a flat spiral Tesla coil. Here are the parts used in this experiment.
