SUMMARY
The discussion centers on calculating the gain of an operational amplifier (op-amp) circuit, specifically using the formula Gain = Vo/Vs. The original poster (OP) attempted to derive the gain but ended up with five equations and five unknowns, leading to an incorrect conclusion of Vs = 0V. An expert pointed out that if the op-amp is assumed to be ideal, the output voltage (Vout) would theoretically approach infinity when connected to an ideal voltage source. The key takeaway is the importance of accurately copying the circuit and connections at the op-amp's inputs.
