Most textbook problems fall into three categories:

Find the equivalent resistance between terminals A and D in the network below (imagine a star-delta diagram where all five resistors are equal to ( R ) in a bridge configuration).

Since all resistors are equal ($R = 3 , \Omega$), the formulas simplify significantly.
