Assume that the ideal op amp in the circuit in Fig. P5.40 is operating in its linear region.
a) Calculate the power delivered to the 16 kΩ resistor.
b) Repeat (a) with the op amp removed from the circuit, that is, with the 16 kΩ resistor connected in the series with the voltage source and the 40 kΩ resistor.
c) Find the ratio of the power found in (a) to that found in (b).
d) Does the insertion of the op amp between the source and the load serve a useful purpose? Explain.
