LECTURE I. NATURE AND ORIGIN OF TRANSIENTS. i. Electrical engineering deals with electric energy and its flow, that is, electric power. Two classes of phenomena are met: permanent and transient, phenomena. To illustrate: Let G in Fig. 1 be a direct-current generator, which over a circuit A con- nects to a load L, as a number of lamps, etc. In the generator G, the line A, and the load L, a current i flows, and voltages e Fig. 1. exist, which are constant, or permanent, as long as the conditions of the circuit remain the same. If we connect in some more lights, or disconnect some of the load, we get a different current i', and possibly different voltages e1 '; but again i' and e' are per- manent, that is, remain the same as

Let, however, in Fig. 2, a direct-current generator G be connected to an electrostatic condenser C. Before the switch S is closed, and therefore also in the moment of closing the switch, no current flows in the line A. Immediately after the switch S is closed, current begins to flow over line A into the condenser C, charging this condenser up to the voltage gi ...

Modern Engineering Reading Prompts

• Transients / damping: Separate the temporary term from the final steady-state term and compare with differential-equation response language.
• Dielectricity / capacity: Check whether the passage treats capacity, condensers, displacement, or dielectric stress as field storage rather than only circuit algebra.
• Field language: Read for whether field language is mechanical, geometrical, causal, descriptive, or simply a convenient engineering model.
• Magnetism: Track flux, reluctance, permeability, magnetizing force, and loss language against modern magnetic-circuit terminology.
• Waves / transmission lines: Map Steinmetz’s wave and line language onto modern distributed constants, propagation velocity, standing waves, and reflections.

Ether-Field Interpretive Boundary

• Transients / damping: Transient collapse, impulse, and surge behavior can be compared with alternative field language, but only as a clearly marked reading.
• Dielectricity / capacity: A Wheeler-style reading may emphasize dielectric compression, field stress, and stored potential, but this page treats that as interpretation unless Steinmetz explicitly says it.
• Field language: Field-pressure or field-gradient interpretations can be explored here only after the explicit source passage and modern engineering translation are kept distinct.
• Magnetism: Centrifugal/divergent magnetic-field readings are interpretive overlays, not automatic historical claims.
• Waves / transmission lines: Standing/traveling wave passages may support richer field interpretations; the page keeps those readings separate from verified Steinmetz wording.

Promotion Checklist

1. Open the full source text and the scan or raw PDF.
2. Verify the chapter boundary and surrounding context.
3. Promote exact quotations only after checking the source image.
4. Move mathematical candidates into canonical equation pages only after formula typography is corrected.
5. Move diagram candidates into the diagram archive only after image extraction, crop verification, and manifest creation.
6. Keep Steinmetz wording, modern translation, and ether-field interpretation in separate labeled layers.
