Fig. 61.—Diagram of tlie Oudin resonator. The Tesia coil is omitted. Tiie current from theinduction coil is connected with the inner tin-foil of the Leyden jars. The outer coat of one Leydenjar is in connection with the resonator, and is also grounded. The outer coat of the other Leyden jaris connected to the handle, H, which, by a slidinsr movement either in the vertical or the horizontaldirection, decreases or increases the amount of winding of the resonator. M is the spark-gap for regu-lating the amount of current. Fig. 62.—The Oudin resonator and Tesla coil, with electrode. (Biddle.)
