Norton’s Theorem Statement

What is Norton’s Theorem?

Norton’s theorem is a popular theorem used for simplifying linear circuits that use multiple independent and dependent sources. It is used to replace circuit elements by Norton’s current source which is in parallel with Norton’s resistance. Basic circuit equations are then written to find the current in different elements of the circuit. It is important to note that the theorem does not apply to non-linear circuits since these circuits don’t follow Ohm’s law....
