HIGH VOLTAGE DEMONSTRATION

E&MP 44.059

Electricity - High-frequency Voltage

no date

An unusual electrical demonstration is the result when Westinghouse engineers impress a 60-cycle current to a specially designed wheel.

The constant throwing off of electrons from the tapered points of the spokes, causes the wheel to revolve and this movement creates the impression of a complete circle of faint blue light.

This is one of the man [?] interesting scientific demonstrations made in the high voltage laboratory of the Westinghouse Electric and Manufacturing Company , at Trafford, Pa.
