The problem statement, all variables and given/known data Design a dc circuit utilizing a 15V voltage battery to provide the following node voltages: +10V, +5V, and -5V w.r.t. a circuit ground node. Select your resistors such that the maximum power demand on the battery does not exceed 1mA. The attempt at a solution I've designed the attached circuit, but I'm not sure how to find the resistance for each circuit. I know that the total resistance of all four circuits must add up to 225000Ω using the calculations attached.
