45. Let the resistors be divided into groups of n resistors each, with all the resistors in the same group connected in series. Suppose there are m such groups that are connected in parallel with each other. Let R be the resistance of any one of the resistors. Then the equivalent resistance of any group is nR , and R eq , the equivalent resistance of the whole array, satisfies 11 1 Rn R m nR m eq == . Since the problem requires R eq = 10 = R , we must select n = m . Next we make use of
