in the early days there was little agreement about the optimal frequency at which this current would “alternate.” As a result even this more flexible voltage system had dedicated wires for 25, 30, 33⅓, 40, 50, 60, 66⅔, 83⅓, and 125 cycles per second. Making it all even worse, when electric companies went out of business, they simply left their wires to molder and fray in the sky.
