Open Question: How to find current and power in resister that's connected parallel and in series?
A 60.0-O resistor is connected in parallel with a 121.0-O resistor. This parallel group is connected in series with a 21.0-O resistor. The total combination is connected across a 15.0-V battery.
(a) Find the current in the 121.0-O resistor.
(b) Find the power dissipated in the 121.0-O resistor.
