1. What happens when \(V_1 > V_2\)? Why?
2. What happens when \(V_1 < V_2\)? Why?
3. What happens when \(V_1 = V_2\)? Why?
4. Explain the differences in the waveforms recorded in Graphs 1 through 3.
5. How would the waveform displays be altered if the oscilloscope inputs were set to AC Coupling instead of DC Coupling in step 4?
6. How would the results of this exercise change if the op amp had a very low gain, say only 1 or 2?
