Mesh Analysis for Circuits Explained

---

This tutorial introduces Mesh Analysis and explains how to use it to solve unknowns in circuits. I find it helpful to label on unknown branch currents before starting the problem, and then substituting the mesh currents in later. This reduces the chance of getting some terms with the wrong sign, but is not a necessary step, as most books will skip that part.
