Day 23 of Linear Circuits. Operational amplifiers are some of the most essential building blocks of electric circuits. While the circuits themselves can be imposing, we show you three basic laws that hold true for all ideal op amps that allow you to quickly simplify and solve op amp circuits. After a quick review, we show you how to solve even more examples.

The material covers all of the lecture material from an twenty-second lecture in a traditional, sophomore-level linear circuits class.
