Martin, Thomas C, Tesla, Nikola · The Electrical Engineer · leaf 188
frequencies obtained from a dynamo machine , and with potentials of no more than one or two hundred thous and volts , the heating effects are considerable , we may imagine how much more powerful they must be with frequencies and po tentials many times greater ; and the above explanation seems , to… … Fig . 111 . have been experimentally demonstrated , at least not to such a remarkable degree . By preventing completely the exchange of the air molecules j the local heating effect may be so exalted as to bring a body to incandescence . Thus , for instance , if a small button , or prefer ably a…
