Tesla coil (a few turns of coarse wire wound around the outside of asecondary winding consisting of a large number of turns of fine wire)and as a consequence, a current of very high frequency, very highvoltage and low amperage is generated in the Tesla secondary. The Tesla coil is particularly adapted for the alternating current, andis employed in most of the portable high frequency machines. Electro-Medicine, Electro-Surgery and Radiology 49 Oudin Current A current of high frequency, high voltage and a low amperage, re-sembling the current from the secondary winding of the Tesla coil, canbe obtained from the DArsonval apparatus, by attaching and properlyadjusting to the solenoid a large coil of fine wire, known as the OudinResonator (Fig. 14).

Fig. 14—Oudin Resonator. High Frequency from the Static Machine The high frequency currents can be also produced from the hyper-static transformer (Fig. 15) connected to the prime conductors of astatic machine. The current thus obtained, does not give a sufficientamperage for the satisfactory application of auto-condensation ordirect DArsonval mefliod (Diathermy), but possesses advantages fordestructive effect over the coil or transformer. Application of High Frequency Currents DArsonval current is administered in the form of Auto-condensa-tion, Auto-conduction, and the direct application or Diathermy;while the currents from the Tesla secondary, the Oudin Resonator or 50 Anthony Matijaca the hyperstatic transformer in the form of Vacuum tube application,Effleuve, and Fulguration.
