A student connects two resistors with unknown resistance values in series, and notes that the equivalent resistance Rs = 725 0. She then connects the same two resistors in parallel, and measures the equivalent resistance to be Rp= = 145 Q. What are the resistances (in ) of each resistor? smaller Ω resistance larger resistance 725 X Write equations for the series and parallel combinations, and combine your equations to find the two pos values. You will need to use the quadratic equation.
