ELECTRICITY FOR ENGINEERS $2

THE introduction of electrical machinery in almost every power plant has created a great demand for competent engineers and others having a knowledge of electricity and capable of operating or supervising the running of electrical machinery. To such persons this pocket-book will be found a great benefactor, since it contains just the information that is required, explained in a practical manner.
