(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data:Two resistors have resistances R1 and R2. When the resistors are connected in series to a 12.0V battery, the current from the battery is 2.00A. When the resistors are connected in parallel to the battery the total current from the battery is 9.00A. Determine R1 and R2.

2. Relevant equations: V=IR Ohms Law

3. The attempt at a solution:

I know that R1 and R2 are the same resistance in both circuits, or R1 and R2 in series = R1 and R2 in parallel.

I also know that the current remains the same in series but changes in the parralel circuit and that the voltage is not constant in series but the same voltage is applied over the resistors in a parallel circuit.

V=I(R1+R2)

R1+R2=V/2.00A=12.0volts/I

Thus V/2.00A=12.0volts/I

I get confused at this point and am not quite sure how to proceed in finding V or I and thus solve for R1 and R2.
