Question : 71 of 100

Marks: +1, -0

Consider two circuits, A and B, each of which has six resistors and each Circuit of resistance R_A and R_B respectively. In each circuit, the resistors are 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 current drawn by circuit A and circuit B are 6 A and 8 A, respectively. Then R_A and R_B will be:

R_A = 20 Ω and R_B = 15 Ω
R_A = 30 Ω and R_B = 15 Ω
R_A = 15 Ω and R_B = 20 Ω
R_A = 15 Ω and R_B = 30 Ω
