1949 - mountain range of electric voltage peaks and valleys

VOLTAGE PEAKS AND VALLEYS

E&MP 72.055

Artificial Lightning

February 17, 1949

No, it isn't a moonlight scene in the Grand Canyon, but a picture of a "mountain range" of electric voltage peaks and valleys.

The curves show how voltage is distributed in a specially-wound copper coil through which a simulated lightning stroke is passed.

The wave lasted only 250 millionths of a second, represented in the width of the model. Length of the model traces the location of the impulse in the winding.
