D 2.33 Use the circuit in Fig. P2.32 as an inspiration to design a circuit that supplies a constant current IL of 3.1 mA to a variable resistance R L. Assume the availability of a 1.5-V battery and design so that the current drawn from the battery is 0.1 mA. For the smallest resistance in the circuit, use 500 . If the op amp saturates at ±10 V, what is the maximum value that R L can have while the current source supplying it operates properly?
