**Aim**

As most mechanical designs are dependent on electric control and drive, basic knowledge of electric circuits is essential for the mechanical engineering student. The goal of the course is to teach the student to compute currents, voltages and power in DC and AC circuits, also for non-sinusoidal and transient signals. Moreover, the student will learn to design basic electronic circuits, mainly with operational amplifiers. Laborations are an important help to learn basic practical measurement and design. The course will give the necessary base for the courses Electric Machines (MIE030) and Measurement Systems for Control (MIE041).
