across the battery is R ' = R 1 + R = 12 . Thus, the current through R ' is (12V)/ R ' = 1.0 A, which is the current through R . By symmetry, we see one-third of that passes through any one of those 18 resistors; therefore, i 1 = 0.333 A. (b) The direction of i 1 is clearly rightward. (c) We use Eq. 26-27: P = i 2 R ' =
