This is a very old video I made when the universe was young, but which continues to have value so it is the continuation of the previous one on MNA. A tutorial. When using Modified Nodal Analysis, MNA, we found in class that all the equations in the circuit fall into one of three groups: controlling variables equations, CTL; equations associated with voltage sources occupying a branch of their own, EVL; and nodal equations, KCL. The first group, CTL equations has caused enough grief to my students as to warrant this dedicated video on writing controlling variables as functions of node voltages, "evil currents" and other controlling variables. That is, how to write CTL equations in many different scenarios.
