Course Description:

The course is about the foundation of electric circuit theory, analysis methods for electric circuits, key terminologies of electrical engineering, and substantial ideas as electrical engineers. It covers the scale of time-invariant lumped circuits, including resistive and dynamic circuits respectively. Its main concerns are about linear circuits while nonlinear resistive circuits are introduced in-depth.
