1. The problem statement, all variables and given/known data Two resistances, R1 and R2, are connected in series with a 12V battery. When R2 is removed (leaving R1 only), the current increases by 0.450 A. When R1 is removed (leaving R2 only), the current increases by 0.225 A. What are the two resistances? 2. Relevant equations [tex]V = IR[/tex] 3. The attempt at a solution I've tried to solve this algebraically, but I keep ending at a point with three unknowns and no realistic way to solve them. The fact that the current bumps are at a 1:2 ratio suggests that something similar should happen with the resistors, but hell if I know where to start.
