Fun examples for teaching linear and nonlinear circuits

Circuit theory is essentially a physically based theory of dynamical systems. To demonstrate basic phenomena example circuits have to be selected and designed. These circuits consist of a few essential elements, which makes it easier to explain the mathematics. But, the abstraction of these simplified circuits can be a hurdle for students. To give students with a strong interest in the application an access to the theory and to add more verve to the lectures, we gathered some circuit examples, which are easy to explain in detail and have an entertaining effect. In this paper, we focus on circuits with at least one reactive element.
