What This Theme Gathers
Section titled “What This Theme Gathers”Passages involving waves, wavelength, frequency, propagation, standing waves, traveling waves, distributed constants, electrical radiation, light, spectrum, ultraviolet, X-rays, and transmission lines.
Reading Layers
Section titled “Reading Layers”Source Evidence
Use the tables and snippets below to locate Steinmetz passages. Exact wording still needs scan verification before canonical quotation.
Modern Reading Prompt
This theme bridges ordinary wave language, distributed-line mathematics, and the radiation spectrum. Keep physical scale and context visible.
Interpretive Boundary
Ether, Tesla-era, and Wheeler-style readings are only secondary layers here. The first task is to identify the wave or radiation context Steinmetz actually uses.

... connection of from 50 to 100 lamps on one circuit. With the exception of a few of the larger cities, all the street lighting by arc lamps in this country is done by constant current systems, either direct current or alternating current. For direct current constant current supply, separate arc light machines have been built, and are still largely used. In these machines, inherent regulation for constant current is produced by using a very high armature reaction and relatively weak field excitation; that is, the armature ampere turns are nearly equal and opposite to the field ampere turns, ...... re connected in series with each other into the arc circuit supplied from the constant potential source, and by separating or coming together, vary in reactance with the load, and thereby maintain constant current. While the alternating current arc lamp is less efficient, that is, gives less light for the same power, than the direct cur- rent arc lamp, the disadvantages of the use of numerous arc machines have led to the extended adoption of alternating cur- rent series arc lighting before the development of the mercury 224 GENERAL LECTURES arc rectifier, which enabled the operation ...Lecture 3: Physiological Effects Of Radiation - 408 hit(s)
