DEPARTMENT
OF ELECTRICAL ENGINEERING
Degree of Bachelor of Science
in Electrical Engineering Requirements
The
course of study of the degree of Bachelor of Science
in Electrical Engineering takes five (5) academic
years and one vacation school to complete and
consists of 164 semester hours. The entire program
follows and includes the general education requirements
of the University of Liberia. Non-technical elective;
must be in the humanities. A foreign language
known to have body of scientific and engineering
literature may be substituted for French and may
also be used as a non-technical elective if continued
past the second year. Technical electives may
be chosen from upper level engineering, science
or math courses but must have departmental approval.
The
electrical engineering curriculum is firmly founded
on a strong base in mathematics, physical and
engineering sciences, social science and communication
skills. Nearly half of the studies apply directly
to the field of electrical engineering.
Inspection
trips to engineering work and plants are made
by electrical engineering students to supplement
their theoretical studies.
Students
desiring to major in Electrical Engineering should
formally request of the chairman of the Division
of Electrical Engineering admittance into the
program upon his acceptance by the College of
Science & Technology. Courses in addition
to demonstrated proficiency and six (6) months
of approved work experience is also required for
graduation.
