Norton Equivalent Circuits

Norton's theorem is a fundamental concept in the field of electrical engineering that allows for the simplification of complex AC circuits. The theorem states that any two-terminal linear network can be replaced with an equivalent circuit that consists of an impedance, which is parallel with a constant current source. Figure 1 shows the AC circu...

Norton's theorem states that any two-terminal linear network can be replaced by an equivalent circuit consisting of a constant current source in parallel with an impedance.

To determine the value of the parallel impedance, the source is replaced with its internal impedance. This resultant circuit's equivalent impedance is the Norton imped...
