First edition; Open Library lists this Internet Archive item for the 1897 W. J. Johnston edition.

The PDF/page images remain the verification base. The archive has preserved the Internet Archive OCR and generated candidate catalogs so this source can now participate in search, source-text browsing, concept concordance, theme evidence, and chapter workbench pages.

  1. Verify title page, edition, and publication metadata.
  2. Correct the section map if OCR headings caused false splits.
  3. Scan-check equations and diagrams before promotion.
  4. Add modern engineering explanations only after source passages are anchored.
  5. Keep edition differences visible when comparing related Steinmetz works.

Generated source dashboard: this section joins the source overview to the book coverage atlas, source text reader, chapter workbench, visual maps, and formula maps. Counts are candidate research aids until scan verification promotes them.

What This Source Currently Gives The Archive

Section titled “What This Source Currently Gives The Archive”

Theory and Calculation of Alternating Current Phenomena currently contributes 30 processed sections and 76,757 candidate OCR/PDF-text words to the archive. Its strongest tracked evidence clusters are Impedance / reactance, Magnetism, Waves / transmission lines.

This is a routing judgment based on processed metadata, not a final historical claim. The strongest next move for any exact quotation, equation, or diagram is still to open the source scan and check the page image.

Source custody

Verify title page, edition, page images, and OCR line boundaries before final quotation.

Mathematics

Use the formula map to locate equations, then correct OCR symbols and preserve Steinmetz notation before modern translation.

Interpretation boundary

Modern engineering and ether-field readings belong after source anchoring, with labels kept visible.
