Problem 18.4

A 9.0-resistor and a 6.0-resistor are connected in series with a power supply. (a) The voltage drop across the 6.0-resistor is measured to be 12 V. Find the voltage output of the power supply. (b) The two resistors are connected in parallel across a power supply, and the current through the 9.0-resistor is found to be 0.25 A. Find the voltage setting of the power supply.
