Bifilar coil. A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as ...
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. [4][7][8][9][10][11] Tesla's original circuits and most modern coils use a simple spark gap to excite oscillations in the tuned transformer. More sophisticated designs use transistor or thyristor [7 ...
Henry Leroy Transtrom (1885–1951) was an American inventor and showman who worked with high voltage electricity. His book, Electricity at High Pressures and Frequencies, [1] (1913) is still used as a guide for constructing homemade Tesla coils. Transtrom was best known for his dramatic stunts and performances with high frequency, high voltage ...

History of the Tesla coil. Henry Rowland's 1889 spark-excited resonant transformer, [1] a predecessor to the Tesla coil. [2] Steps in Tesla's development of the Tesla transformer around 1892. [3] (1) Closed-core transformers used at low frequencies, (2-7) rearranging windings for lower losses, (8) removed iron core, (9) partial core, (10-11 ...
TeslaBifilarColor.svg. English: Bifilar coil in Nikola Tesla's United States patent 512,340 of 1894. Tesla explains that in some applications (which he does not specify) the self-inductance of a conventional coil is undesired and has to be neutralised by adding external capacitors. The bifilar coil in this configuration has increased self ...
Resonant inductive coupling or magnetic phase synchronous coupling[4][5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
Coil winding technology. In electrical engineering, coil winding is the manufacture of electromagnetic coils. Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill ...
