[4pts] Consider the network above with V1 = 8V, V2 = 3V, and R = 4kΩ. Treat the op-amp as real, with β = 1.5 × 105, Rx = 1.8MΩ, and Ry = 24Ω. What is the voltage vx across the input terminals? vx = What is the current ix through the input terminals? ix = What is the "ideal" output voltage (treating the op-amp as ideal)? videal = What is the difference between the ideal and real output voltage? vreal – videal =
