Abstract :
THE ELECTRICAL engineer has been preparing for this war for 20 years or more, although he may not have been aware of it. He has been rapidly gaining knowledge in practically every branch of electrical engineering since World War I; and as this knowledge accumulated through research, experiment, and analysis, he has interpreted it into machines, devices, systems, and practices for peacetime or civilian use. Since early in the emergency period preceding the present war, his efforts have been shifted to the adaptation and application of this knowledge to war machines and practices.
