Abstract

Experiments on Electric Oscillations. April 1st Monday Used small induction coil for preliminary experiments. Its length is 18 cms its diam 8.5. The res of its primary 0.14 its secondayr 7500 w.##Activated the primry and its automatic vibrator with the 6 volt dynamo. Connected the secondary terminals to an air condenser formed of two insulated brass disks each 17.4 cms in diam and separated by about 0.5 of air space. Next took a spark micrometer whose electrodes are taper4ing points and joined them by a wire of black covered coper some 150 cms long. Twisted this covered wire round the rods of the air condenser.
