Electricity and Magnetism Electric and Magnetic Circuits A Text-book of Electrical Machinery [PDF]
Nature, 1904 THE best method of training electrical engineers will probably remain a subject of discussion so long as the profession continues to be a profitable one. Whether recourse should be had to the factory or to the technical college; whether a combination of these two is desirable or necessary, and if so, in what manner they should be combined; and whether ...
