Two resistances, R1 and R2, are connected in series across a 12.0-V battery. The current increases by 0.200 A when R2 is removed, leaving R1 connected across the battery. However, the current increases by just 0.130 A when R1 is removed, leaving R2 connected across the battery. Find (a) R1 and (b) R2. (a) Number Units (b) Number Units
