As the curriculums of electrical engineering programs became over crowded, many schools began combining electromechanical energy conversion and power systems analysis courses. There were no books to fit this trend, and using two books was uneconomical and confusing. Today, almost 15 % of the Universities in the US and the Canada require a combined course.
