A 6 V battery output is divided down to obtain two output voltages. Three 2.2 kΩ resistors are used to provide the two taps. The two output voltages are

The parallel combination of a 470 Ω resistor and a 680 Ω resistor is in series with the parallel combination of four 2 kΩ resistors. The total resistance is

Two 3.3 kΩ resistors are in series and this series combination is in parallel with a 4.7 kΩ resistor. The voltage across one of the 3.3 kΩ resistors is 12 V. The voltage across the 4.7 kΩ resistor is
