Electronics is all about differential equations. > Circuit simulation programs take a text netlist describing the circuit elements (transistors, resistors, capacitors, etc.) and their connections, and translate this description into equations to be solved. The general equations produced are nonlinear differential algebraic equations https://en.wikipedia.org/wiki/SPICE https://en.wikipedia.org/wiki/SPICE All the way down to transistors and other basic elements > These models are very computer intensive, involving detailed spatial and temporal solutions of coupled partial differential equations on three-dimensional grids inside the device https://en.wikipedia.org/wiki/Transistor_model https://en.wikipedia.org/wiki/Transistor_model
