HI&H FREQUENCY AND HIGH POTENTIAL CURRENTS. 391lustration. A machine was used giving about 20,000 alternationsper second. Two bare wires about twenty feet long and twomillimetres in diameter, in close proximity to each other, wereconnected to the terminals of the machine at the one end, andto a condenser at the other. A small transformer without aniron core, of course, was used to bring the reading within rangeof a Cardew voltmeter by connecting the voltmeter to thesecondary. On the terminals of the condenser the electromotiveforce was about 120 volts, and from there inch by inch it graduallyfell until at the terminals of the machine it was about 65volts. It was virtually as though the condenser were a generator,and the line and armature circuit simply a resistance connectedto it. The writer looked for a case of resonance, but hewas unable to augment the effect by varying the capacity verycarefully and gradually or by changing the speed of the machine.A case of pure resonance he was unable to obtain.When a condenser was connected to the terminals of the machinethe self-induction of the armature being first determinedin the maximum and minimum position and the mean value takenthe capacity which gave the highest electromotive force correspondedmost nearly to that which just counteracted the self-inductionwith the existing frequency. If the capacity was increasedor diminished, the electromotive force fell as expected.With frequencies as high as the above mentioned, the condensereffects are of enormous importance. The condenserbecomes a highly efficient apparatus capable of transferringconsiderable energy.In an appendix to this book will be found a description of theTesla oscillator, which its inventor believes will among other greatadvantages give him the necessary high frequency conditions,while relieving him of the inconveniences that attach to generatorsof the type described at the beginning of this chapter.
