     The model above has 4 variables but only three equations, there is no equation specifying the value of `r` since `r` is an input. This means that only unbalanced models can be linearized, or in other words, models that are balanced and can be simulated _cannot_ be linearized. To learn more about this, see [How to linearize a ModelingToolkit model (YouTube)](https://www.youtube.com/watch?v=-XOux-2XDGI&t=395s).
