Document Summary

The last section demonstrated the creation of an equivalent circuit by finding the open-circuit voltage and the short-circuit current. While we used the short-circuit current for the determination of rthevenin, we didn"t use it for anything else. We can also create a representative equivalent circuit using the short-circuit current. This current is known as the norton current (in). The equivalent circuit looks like the one shown below. Note that this time the resistance is in parallel instead of in series, but it is still called. It would be just as correct to call it. It is found in the same manner as it was when you were thevenizing a circuit. The main difference is that instead of looking for a v" open-circuit, we are looking for an i" short-circuit. Replace the sources and place a short circuit across the open terminals vacated by the load.
