Experiments with Alternate Currents of Very High Frequency and Their Application to Methods of Artificial Illumination: Nikola Tesla's Classic Lecture - Paperback

Nikola Tesla's famous 1891 lecture on high-frequency alternating currents helped open the way toward modern electrical experimentation, wireless energy concepts, and new methods of artificial illumination. Delivered before the American Institute of Electrical Engineers at Columbia College on May 20, 1891, this paper presents Tesla's investigations into currents of extremely high frequency and their striking effects on lamps, coils, vacuum tubes, electrical discharge, and the production of light.

Tesla moves beyond ordinary electrical engineering into the experimental frontier where electricity becomes visible, luminous, and almost theatrical. He describes machines capable of producing enormous numbers of reversals per minute, investigates how lamps may glow near induction coils, and explores the practical problem of creating a more efficient source of light. The work is technical, but it also captures Tesla's genius for demonstration: electricity is not merely calculated here, but made radiant, strange, and persuasive.

First presented in 1891, Experiments with Alternate Currents of Very High Frequency and Their Application to Methods of Artificial Illumination remains an important primary text for readers interested in Tesla, alternating current, electrical invention, early lighting technology, radio-era precursors, and the history of experimental physics. It is especially useful for collectors of Tesla's writings, students of nineteenth-century science, and readers tracing the development of high-voltage and high-frequency electrical research.
