Elementary lectures on electric discharges, waves and impulses, and other transients
Charles Proteus Steinmetz's 1914 lecture course on electric discharges, waves and impulses, published by McGraw-Hill in New York and London for electrical engineering students and practicing engineers. The plates are line diagrams of oscillating current and voltage curves—damped sine trains, sharp transient spikes, exponential envelopes—labeled i₀, i₁, i₂ against baseline axes, usable as clean wave motifs and technical chart ornament.
