ENGR-491 Electrical Engineering 1-4 hours An opportunity in which an electrical engineering student works closely with an industrial advisor employed at an area firm. Specific attention is given to solving a particular problem in that industry or firm by applying electrical engineering design method– ology. A faculty advisor assists in supervision of and approval of the internship, including assessment of the number of credit hours. A final report (minimum 1000 words) describing briefly the experience -- including the problem and solution -- is required. Three credit hours of engineering electives can be satisfied by three or four hours of internship. Prerequisite: Permission of faculty advisor.
