1. The problem statement, all variables and given/known data Two resistances, R1 and R2 are connected in a series circuit across a 12V battery. The current increases by 0.20A when R2 is removed leaving R1 connected across the battery. However, the current increases by just 0.10A when R1 is removed, leaving R2 connected across the battery. Find (a) R1 and (b) R2. 2. Relevant equations I = 12/(R1+R2) I + 0.20A = 12 / R1 I + 0.10A = 12 / R2 3. The attempt at a solution I = 12 / (12/I + 0.20A) + 12/ (12/I + 0.10A) I = I + 0.20A + I + 0.10A I = 2I + 0.30A -I = 0.30A I = -0.30A. Then, I plugged them back into equation 2, 3 but got the wrong answers. The correct answers are 35 OHM and 50 OHM. PLease help!?
