Not illustrated. 1908 edition. Excerpt: ...will be so small that practically no current will be established in the pipe. This is analogous to the condition of the insulated wire in the above experiment, when the plate to which it is connected is reduced to an extremely small size. If we imagine the distended bag to be surrounded by super-heated dry air, the analogy will become still more perfect inasmuch as the water which oozes through the cloth is instantly converted into steam, which radiates in a cloud from all parts of the bag. This radiating nebula is very similar to the vibratory aura or the rapidly alternating electro-static field given off by the insulated plate or by the body of a patient connected to a terminal of a Tesla Coil. (See Fig. 101.) That an electrical current of high voltage and considerable amperage actually flows through the wire connecting the plate to the terminal may be demonstrated in a number of ways. If the wire be cut at its middle point, and the two ends united through a hot wire mil-ammeter the latter will register a current from one-twentieth to one-half an ampere. If an ordinary sixteen-candle power incandescent lamp be substituted for the meter, its filament will become incandescent. A fine iron or platinum wire similarly connected will become white hot and may even be melted. All of the above experiments demonstrate the high amperage of the current. In order to demonstrate the great voltage of the current in the wire, different means must be employed from those used with continuous or Low-frequency Currents. Up to the present time no satisfactory instrument for the measurement of the voltage of High-frequency Currents has been devised, but while we cannot measure it accurately it is easy to demonstrate that the current in the wire is of...
