The performance characteristic of electric equipment depend upon the materials of which it is made, and upon the arrangement and dimensions of these parts. In this course this relationship for simple equipment, such as resistors and magnets, is studied mainly by computation methods. Some time is taken here for the layout of machinery locations on the floors of a building, which gives some practice in the use of surveying instruments. The quantitative study of materials and their arrangement in electric machinery is carried further into the windings of direct and alternating current machinery, including transformers if time is available. _Texts: Nims, “Electric Machine Design Notes”; Busse, “Surveying Notes”._ EE 71 Electricity. This is the general course adapted to the needs of chemical and mechanical engineering students. It is a lecture, recitation and problem course in the fundamental units and their application to the electric circuits and machines. The topics are as follows: Magnetism, induction, electric current, pressure and resistance, electric power and energy; electric, magnetic and electro-static circuits; single and polyphase alternating current circuits by graphical, analytical and complex quantity methods. _Texts: Dawes, “Electrical Engineering”, Vol. I; Dawes, “Electrical Engineering”, Vol. II; McKone, Laboratory Manual “Applied Electricity”._ EE 75 Electricity. This is a general survey course adapted to civil engineers. It is not followed by laboratory experience. It treats the fundamental units and their application to electric circuits and electric machinery, both direct and alternating current. It is made as broad as possible for these students who have but limited time to give to the subject. _Text: Timbie, “Elements of Electricity”._ EE 81 Applied Electricity. Prerequisite, EE 71. This is the electric machinery course for mechanical engineering students. It offers experience in the wiring, measurement and operation of the usual direct and alternating current machines. The proper application of these machines in industry is treated. The classroom work is supplemented by a machine laboratory course. _Texts: Dawes, “Electrical Engineering”, Vols. I & II; McKone, Laboratory Manual “Applied Electricity”._ EE 83 Applied Electricity. Prerequisite, EE 71. This is the electric machinery course for chemical engineering students. It is similar to EE 81 except that it requires but one semester and therefore is much abridged. _Texts: Dawes, “Electrical Engineering”, Vols.
