Image: Tesla drawing 1899 - Evolution of Tesla transformer

Description: Drawing by Serbian American inventor Nikola Tesla showing stages in his evolution of the high frequency resonant transformer used in his Tesla coil. He developed the Tesla transformer around 1891-1892 although this drawing was published in 1899. He describes the steps in the accompanying article: (1) Closed-core transformers used at low frequencies (2-7) Rearranging windings for lower losses (8) Removed iron core (9) Partial core (10-11) Final conical Tesla transformer (12-13) Tesla coil circuits The high Q RF transformer designs invented by Tesla have been used in radio transmitters to the present day.
