Answer» P / Q = R / S' S' = QR / P = 2*3/2 = 3 1/S + 1/r = 1/S' 1/4 + 1/r = 1/3 r = 12 ohms.connect a resistance of 12 ohms, in parallel with the resistance S (4 ohms) to balance the wheat-stone bridge. option (2) is the right answer? option (3) is the right answer option 3. is the correct answer of the given question |
