An introduction to electric circuits in preparation for the FE exam, and the application of electric power systems to mining. The course reviews physical principles applicable to electrical circuits, basic circuit laws and their application to simple DC and AC circuits, including ideal transformers. Three phase circuits and their analysis in simple cases and the electrical characteristics of typical AC and DC motors are studied.  This material is then extended to typical mining operations. Particular attention is focused on the relationship between production rates and power usage and associated costs; electrical safety; and common power system terminology with which mining engineers should be conversant.
