                  The students are advised to solve this problem by converting the three

               resistances forming star point at N into an equivalent delta touching points A,
               B, and C and then solve by considering series parallel connections and arrive
               at the same value of R     AB .



               Example 2.39    Using star–delta transformations calculate the equivalent

               resistance of the network between terminals A and B. All resistances in Fig.
               2.135 are in Ohms.
