Thevenin Equivalent Circuits. Introduction In each of these problems, we are shown a circuit and its Thevenin or Norton equivalent circuit.

To convert the above Thevenin circuit to a Norton circuit, the terminals A and B are short-circuited. The Norton Current is then the Thevenin Voltage V TH divided by the Thevenin resistance, R which will be the same value in the Norton equivalent circuit.
Norton Example. Replacing a network by its Norton equivalent can simplify the analysis of a complex circuit. In this example, the Norton current is obtained from the open circuit voltage (the Thevenin voltage) divided by the resistance r.
