Circuit Theory

Moving from the full form of Maxwell’s Equations to the simpler assumptions appropriate for low-frequency lumped element network theory reduces analysis and design of electrical systems to the task of writing loop and/or nodal equations describing an electric circuit. I teach introductory network theory in my Physics classes.

More advanced linear circuit methods such as Laplace transform techniques permit modeling lumped element systems, including the effects of initial conditions, by introducing Laplace transformed circuit elements into a circuit’s basic description.


Here is a basic RLC Resonance circuit:


And here is the frequency response
