Problem 5.4 (Nilsson Riedel) Electric Circuits 10th Edition - Ideal Op-Amp

Problem 5.4

The op-amp in the circuit in Fig. P5.4 is ideal
a) Calculate vo if va = 1.5 V and vb = 0 V
b) Calculate vo if va = -0.5 V and vb = 0 V
c) Calculate vo if va = 1 V and vb = 2.5 V
d) Calculate vo if va = 2.5 V and vb = 1 V
e) Calculate vo if va = 2.5 V and vb = 0 V
f) If vb = 2 V, specify the range of va such that the amplifier does not saturate
