Electrical Engineering 2 (5 cr)

Objective

After completion of the course the student
• understands how electrical energy is produced, transmitted, distributed and balanced
• knows the most common parts of the electrical system of buildings
• recognises the differences between direct and alternating current and their use in electric power technology
• knows the operating principles of electric machines and the control of machines using power electronics.
• understands the fundamental need of presenting the voltages, currents, powers etc. as complex variables and is able to apply these to the basic theorems of electrical engineering, such as Ohm’s law and Kirchoff’s law
• understands the concepts of complex power and is able to analyse the power levels based on complex voltages, impedances and currents
• is able to analyse more complex circuits using the superposition principle and source transformations
• understands the concepts of amplification, attenuation and their dB representations
• is able to conduct attenuation / amplification / frequency response measurements at the electronics lab using an oscilloscope and a function generator.
