Kirchhoff’s Current Law (KCL) – How to Solve Complicated Circuits

If you know Ohm’s Law and parallel and series circuits, you have a good start but now you need to know how to solve complicated circuits. We’re going to learn about Kirchhoff’s Current Law, frequently known as KCL, and how we can use that law to do nodal analysis on basic or complicated circuits. This knowledge of KCL and nodal analysis will make complicated circuits simple and simple circuits even… simpler? More simple? Easier! In this video, we cover these concepts, try to understand these concepts intuitively, learn the best way to solve complicated circuits, and then do a few circuit problems with solutions to put that theory into practice.
