A power supply has a fixed output voltage of 12.0V, but you need VT = 3.5 V

Question:

A power supply has a fixed output voltage of 12.0V, but you need VT = 3.5 V output for an experiment.

(a) Using the voltage divider shown in Fig. 19-78, what should R2 be if R1 is 14.5 Î©?

(b) What will the terminal voltage be VT if you connect a load to the 3.5-V output, assuming the load has a resistance of 7.0Î©?
