Edge/source evidence summary:

Prerequisite Type Confidence Evidence level Note Sources
Electricity (electricity) enabling 74% textbook Alternating current is a form of electrical power, so the electricity node is a direct enabling foundation.
Electrical Grid (Early Distribution) (electrical_grid_early_distribution) historical_predecessor 72% textbook Early electrical distribution supplied the deployment context that AC systems improved through voltage transformation and long-distance transmission.
Power Transformers (power_transformers) required 82% textbook Voltage transformation is the central scaling advantage of AC power transmission.
