This is I Norton. Remove the short circuit and determine the voltage at terminals a-b. This should be the same value as determined earlier. Use the relationship, RN = V open circuit/I short circuit to obtain the Norton equivalent resistance. This should be the same as the Thevenin resistance found earlier. Draw your Norton equivalent circuit as shown below. Figure 2. 13: Norton Prelab Exercise equivalent circuit.
