3–88 In this problem, you will design two interface circuits that deliver 150 V to the 5-kΩ load shown in Figure P3−88.

(a) Design a parallel resistor interface to meet the requirements.

(b) Convert the source circuit to its Thévenin equivalent and then design a series interface to meet the requirement.

(c) If minimizing the power that the current source delivers is the primary consideration, which of your two designs best meets the requirement?
