Norton's Theorem for DC Electrical Circuits

Norton's theorem is a useful tool for creating a simplified and equivalent version of a linear, bilateral circuit. The basic idea is that you can reduce any linear bilateral circuit (ie., one with only resistors, voltage sources and current sources) down to an equivalent circuit with a single current source and a single shunt (parallel) resistor. This video explains the idea behind Norton's theorem and then works through an example demonstrating the process of converting to a Norton equivalent circuit
