This Daily Study Group explores the fundamentals of electric circuits using Wolfram Language and Wolfram System Modeler. User-friendly diagrams, visualizations and models help to demonstrate, in an intuitive way, how electric circuits behave. The first two sessions of this Study Group will cover circuit components and basic theoretical concepts. Later sessions will focus on circuit analysis methods and how to analyze and design circuits using operational amplifiers. Lessons used in this Study Group are taken from the new Wolfram U interactive course Introduction to Electric Circuits.
