Chapter 2, Problem 2.78(choose chapter or problem)
The two circuits in Fig. P2.78 are intended to function as voltage-to-current converters; that is, they supply the load impedance ZL with a current proportional to vI and independent of the value of ZL. Show that this is indeed the case, and find for each circuit iO as a function of vI. Comment on the differences between the two circuits.
