"D'Arsonval apparatus", invented by French physicist and doctor Jacque Arsene D'Arsonval around 1890 used in an obsolete Victorian-era medical field called electrotherapy. It was a high frequency resonant "oscillation transformer" similar to a Tesla coil without the secondary winding, which generated high voltage, high frequency electricity. It consisted of an induction coil (rear) that generated a high voltage of around 4 - 15 kV. This repeatedly charged the two Leyden jar capacitors, which repeatedly discharged with a spark through the spark gap. The capacitors together with the solenoid coil (front) formed a tuned circuit and the spark excited damped oscillations in the tuned circuit. The device produced an oscillating voltage of 20 - 30 kV with substantial current at frequencies of around 300 kHz - 5 MHz. Wires from both ends of the coil to electrodes applied the current to the patient's body. It was used for diathermy (deep heating of tissue) and several other therapies.
Nikola Tesla (1856–1943) Serbian American inventor and engineer who discovered and patented the rotating magnetic field, the basis of most alternating-current machinery. He also developed the three-phase system of electric power transmission. He immigrated to the United States in 1884 and sold the patent rights to his system of alternating-current dynamos, transformers, and motors to George Westinghouse.
