Question:

A power supply has a fixed output voltage of 12.0 V, but you need VT = 3.0V for an experiment.

(a) Using the voltage divider shown in Fig. 19-66, what should R2 be if R1 is 10.0Ω?
(b) What will the terminal voltage VT be if you connect a load to the 3.0 V terminal assuming the load has a resistance of 7.0 Ω?
