Question : 45 of 100

Marks: +1, -0

Consider two circuits, A and B, each of which has 12 resistors each 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 30 V battery with negligible internal resistance is connected across each circuit separately, and the current drawn by circuit A and circuit B are 10 A and 18 A, respectively. Then R_A and R_B will be:

R_A = 26 Ω and R_B = 25 Ω
RA = 36 Ω and RB = 15 Ω
RA = 26 Ω and RB = 20 Ω
RA = 36 Ω and RB = 20 Ω
