The circuit shown in Fig. P2.8 c), (on page 111 of the Text) using an op amp with a gain of 104 VN, is found to have an output voltage of +10 V. What is the voltage required at the inverting input terminal of the op amp for this to occur? What is the current through the grounded 10 Ica resistor? What is the pre-cise input voltage, ub you would expect? (Hint: First, consider this question assuming that the gain (104) is very high. Then, refine your answer with a calculation in which a very small error correction is made).
Using the multimeter, measure and record the actual resistance values of the resistors. Set the DC power supply to provide 15V (verify with your multimeter), and build the circuit in Figure 1 on your breadboard.
Include worked solution, a discussion of any differences in the theoretical and measured values and screenshots that show your measurements and paste them into a document
