Summary
This lecture demonstrates experiments with alternating currents of high potential and high frequency, arguing for the desirability of very high frequencies to achieve significant results and generate the necessary high potentials for the experiments. Nikola Tesla presents these findings, building upon previous work and aiming to make the current study self-contained for a London audience. The core of the investigation focuses on the specific characteristics and effects of alternating currents when both potential and frequency are elevated.
The lecture details experiments that showcase phenomena achievable only with these specific electrical conditions. While acknowledging that some experiments might function with lower frequencies, Tesla emphasizes that high frequencies are crucial not only for yielding a greater variety of effects but also as a practical method for producing the high potentials required for most of the contemplated demonstrations.
Key concepts
- High Potential Alternating Currents — Electrical currents that oscillate and possess a significantly elevated voltage.
- High Frequency Alternating Currents — Electrical currents that oscillate at a very rapid rate, a key factor for producing specific experimental results.
- Induction Apparatus — Devices used in the experiments that rely on electromagnetic induction, particularly to achieve high potentials through the use of high frequencies.

Description: A lecture delivered before the Institution of Electrical Engineers, London, February 1892. Complete with illustrations.A short time ago I had the honor to bring before our American Institute of Electrical Engineers some results then arrived at by me in a novel line of work. I need not assure you that the many evidences which I have received that English scientific men and engineers were interested in this work have been for me a great reward and encouragement. I will not dwell upon the experiments already described, except with the view of completing, or more clearly expressing, some ideas advanced by me before, and also with the view of rendering the study here presented self-contained, and my remarks on the subject of this evening's lecture consistent.
