Educational goals

The main objectives of the course is to provide the fundamentals of electric circuits and to develop the tools of linear circuit analysis. Another objective is to prepare students to take some more advanced courses in the area of circuits and electronics. Upon completion of the course, students should be able to do the following:

• Identify and describe the basic components of electric circuits and combine them to design simple electrical circuits.
• Identify and explain the different types of source and resistor connections.
• Apply Ohm’s Law and Kirchhoff's current and voltage laws to simple and complex circuits and produce the basic equations that describe their function.
• Calculate the required values of current or voltage in a circuit, by using systematic methods (mesh analysis), superposition, source transformation and the Wye-Delta transformations.
• Calculate Thevenin’s and Norton’s equivalent circuits and design circuits to provide maximum power to a load.
• Evaluate each circuit and compare the different techniques with which it can be resolved.

General Skills

• Search, analysis and synthesis of information by using the appropriate means and technology.
• Desicion making.
• Independent and cooperative work.
• Respect to the natural environment.
• Criticism and self-criticism ability.
