Why This Source Was Added
Section titled “Why This Source Was Added”Early expanded AC edition; important for tracking the growth of impedance, reactance, transformer, harmonic, and symbolic-method language.
Candidate Processing State

Edition And Custody Note
Section titled “Edition And Custody Note”Third edition, revised and enlarged; Open Library and Wikimedia Commons point to this Internet Archive item.
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.
Promotion Path
Section titled “Promotion Path”- Verify title page, edition, and publication metadata.
- Correct the section map if OCR headings caused false splits.
- Scan-check equations and diagrams before promotion.
- Add modern engineering explanations only after source passages are anchored.
- Keep edition differences visible when comparing related Steinmetz works.
Source Research Dashboard
Section titled “Source Research Dashboard”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 32 processed sections and 91,217 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.

Verification Focus
Section titled “Verification Focus”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.
