History of the Transformer

The work takes listeners on a concise tour of the transformer’s early days, beginning with Michael Faraday’s 1831 induction experiments. It explains how the simple arrangement of two coils—one powered by a battery, the other linked to a galvanometer—revealed the principle of induced electromotive force that underpins every modern transformer. By describing Faraday’s iron‑ring apparatus and its magnetic circuit, the narration sets a clear foundation for the technology that would later light cities.

From that starting point the author follows the succession of inventors, patents, and practical refinements that turned a laboratory curiosity into a cornerstone of alternating‑current distribution. The text gently corrects the tangled claims found in nineteenth‑century journals, showing how engineers like Zipernowsky, Déri, and Bláthy built on the original ideas. Written with the clarity of a seasoned electro‑technical editor, the book offers an engaging, factual snapshot of the transformer’s birth and its early impact on electric lighting.
