EIMT 44 - AC/DC Systems and Equipment

Course Description

  • Prerequisite: "C" in EIMT 30 and in EIMT 32
  • Corequisite: EIMT 46
  • EIMT majors only

This course is designed to advance the student into electrical principles of direct-current and alternating-current circuits and equipment. Emphasis is placed on the theory, operating characteristics and control of AC and DC machinery.
