| Hysteresis law and magnetic loss | hysteresis, magnetic-fields, dielectric-loss, inductance-capacity | Acquire primary scan or publisher PDF, then transcribe equations and any magnetic-loss curves against page images. |
| Complex quantities and the birth of engineering phasors | complex-quantities, symbolic-method, impedance, reactance, admittance | Verify against the International Electrical Congress proceedings scan before promoting any quotation or equation. |
| General equations of the electric circuit | symbolic-method, complex-quantities, transient-phenomena, impedance, distributed-constants | Acquire article text and preserve equation/page mapping before adding formulas to the curated math canon. |
| General circuit equations, continuation | symbolic-method, transient-phenomena, distributed-constants, impedance | Acquire together with the 1908 paper so the series can be decoded as a sequence. |
| Mechanical forces, magnetic stress, and field language | magnetic-fields, hysteresis, ether, inductance-capacity | Acquire the article and separate explicit Steinmetz field-force language from later ether-field interpretation. |
| Lightning phenomena in electric circuits | lightning-surges, transient-phenomena, electric-waves, distributed-constants | Acquire the proceedings scan and extract impulse-wave diagrams only after page-image verification. |
| Natural period of transmission lines and lightning discharge | distributed-constants, lightning-surges, electric-waves, transient-phenomena | Locate the Electrical World issue or a library scan before any source text is generated. |
| Disruptive strength under transient voltage | lightning-surges, dielectric-loss, transient-phenomena | Acquire primary scan and keep Hayden/Steinmetz authorship visible in citations. |
| Instability of electric circuits | transient-phenomena, oscillation-damping, lightning-surges | Acquire article scan and route suspicious OCR formulas into review, not curated math. |
| Theory of impulse currents | lightning-surges, transient-phenomena, distributed-constants | Acquire article and scan-check each equation before adding to canonical formula pages. |
| Oxide film lightning arrester | lightning-surges, dielectric-loss, electric-apparatus | Acquire scan and keep apparatus claims separate from general transient theory. |
| Condenser discharges through a gas circuit | transient-phenomena, oscillation-damping, dielectric-loss | Acquire article and verify whether figures or oscillograms exist before visual promotion. |
| Cable charge, discharge, and distributed capacity | distributed-constants, transient-phenomena, inductance-capacity, electric-waves | Acquire article and page-map charge/discharge curves before diagram promotion. |
| Arcing grounds and cumulative surges | lightning-surges, transient-phenomena, oscillation-damping, electric-waves | Acquire scan and separate source equations, apparatus behavior, and later interpretive synthesis. |
| The future of electricity | historical-context, power-systems, social-electricity | Acquire public scan or HathiTrust-accessible page images before OCR. |
| Systems of electric transmission and distribution | power-systems, alternating-current, distributed-constants | Verify public text availability and edition identity before processing. |
| Patent-to-theory bridge | electric-apparatus, lightning-surges, illumination, hysteresis, inductance-capacity | Normalize the full authority corpus before claiming completeness; the current bridge is seeded examples only. |
