Experiments with Alternate Currents of High Potential and High Frequency

Book Excerpt: n, so it seems that; in all branches of industryalternating currents--electric wave motion--will have the sway.One reason, perhaps, why this branch of science is being so rapidlydeveloped is to be found in the interest which is attached to itsexperimental study. We wind a simple ring of iron with coils; weestablish the connections to the generator, and with wonder anddelight we note the effects of strange forces which we bring intoplay, which allow us to transform, to transmit and direct energy atwill. We arrange the circuits properly, and we see the mass of ironand wires behave as though it were endowed with life, spinning a heavyarmature, through invisible connections, with great speed andpower--with the energy possibly conveyed from a great distance. Weobserve how the energy of an alternating current traversing the wiremanifests itself--not so much in the wire as in the surroundingspace--in the most surprising manner, taking the forms of heat, light, mechanical energy, and, most surprisingRead Mor
