Understanding the Answer
Let's break down why this is correct
Answer
In practical op‑amp circuits the output voltage is mainly set by the feedback network, so the circuit behaves in a predictable linear way. The feedback forces the op‑amp to work in its linear region, keeping the output proportional to the input difference. Because the feedback defines the effective gain, the output follows a straight‑line relationship with the input. For example, with a 10× feedback resistor ratio, a 1 V change at the input produces a 10 V change at the output. This linearity makes the op‑amp a reliable tool for amplifiers and filters.
Detailed Explanation
When you connect a resistor network to the output of an op-amp, the network tells the amplifier how much to amplify the input difference. Other options are incorrect because Resistors alone do not decide the final voltage; Capacitance stores charge, but it does not set a steady output level.
