Consider two circuits, A and B, each of which has six resistors and each circuit has resistance R A and R B respectively. In each circuit, the resistors are connected in such a way that the net resistance of each circuit is the minimum. Now a 20 V battery with negligible internal resistance is connected across each circuit separately, and the currents drawn by circuit A and circuit B are 6 A and 8 A, respectively. Then R A and R B will be:
