Question
2. The circuit in Fig. 2 utilizes an ideal op amp. \text { (a) Find } I_{1}, I_{2}, I_{3}, I_{L} \text {, and } V_{x} \text {. } (b) If
Vo is not to be lower than –13 V, find the maximum allowed value for R1. (c) If RL is varied in the range 100 2 to 1 k2, what is the corresponding change in ILand in Vo?
