Why Three Wires? Tesla and the Timing Behind AC Power
Three separate circuits seem to need six wires. How can a balanced three-phase system work with three? Follow the timing, then compare the modern explanation with Tesla's actual 1888 patent and the engineers who built practical polyphase installations. Original documents, modern context footage, and explanatory models are identified separately. This is electrical history, not a wiring guide.
