(2) LEARNING OBJECTIVES

Learning Objectives

 

 

The purpose of the theoretical part of the course is to help students:

-        Understand the basic concepts of electricity and  magnetism and the electrical elements required in their field.

-        Use their knowledge in technical applications

-        Aquire skills for solving problems in applications

-        Aquire the background knowledge so as to be able to attend specialty courses

The purpose of the lab sessions is to help students: 

-        Further understand aspects of electromagnetism that they have been taught theoretically.

-        Verify experimentally and put applications in practice

-        Make use of electrical measurement instruments and do measurement procedures.

-        Learn measurement processing , extract and evaluate outputs

-        Familiarize themselves with the use of simulators and computers

-        Have practice on composing a technical scientific assignment.
