Second, determine the equivalent resistance of the remaining circuit by “looking into” the terminals; the equivalent resistance is the value of Rth or RN. By Short-Circuit Current – This method applies during analysis of a circuit or in testing an actual circuit that can safely have a short circuit at its terminals.

Find the equivalent resistance for the following networks. i) ii) iii) If you have a single potential source, then finding the equivalent resistance is a very effective way to analyze a circuit. The general strategy is to find the equivalent resistance and use that to find the current provided by the source i = V/Req.
