Understanding the Answer
Let's break down why this is correct
Answer
Op‑amp gain is the main lever that lets you shape how a circuit behaves, just as high‑voltage transmission lines are the main levers that let a power system shape how electricity is delivered over long distances. In both cases you tune a single, powerful component to control a whole system. For a designer, selecting the right gain lets you amplify signals with the desired precision; for an engineer, choosing the right transmission line lets you deliver large amounts of power with minimal loss. For example, a 10‑gain amplifier boosts a weak microphone signal to a usable level, while a 345‑kV line carries power from a distant plant to a city with very low resistance losses. Thus, high‑voltage transmission lines are to power distribution what op‑amp gain is to circuit design.
Detailed Explanation
High gain lets an op-amp produce the needed output with small error signals, making the circuit stable and efficient. Other options are incorrect because It sounds like higher voltage would create more resistance, but actually engineers design these lines with very low resistance; High voltage does make safety harder, but utilities solve this with insulation, grounding, and safety switches.
