Electric Generators

July 3, 1934

A high-ampere generator is about to discharge in this photograph.

Notice that the men watching the generator are stuffing their fingers into their ears to protect them from the loud report when the current is discharged.

The loud report from the electrical discharge, we see on stormy nights as lightning, is thunder.
