What is the effect of negative feedback in an operational amplifier circuit?

Step 1: Understand what an operational amplifier (op-amp) is. It is an electronic device that can amplify voltage signals.
Step 2: Learn about feedback in circuits. Feedback is when part of the output is fed back to the input.
Step 3: Know the difference between positive and negative feedback. Negative feedback reduces the output, while positive feedback increases it.
Step 4: Recognize that negative feedback is used in op-amp circuits to control the gain (how much the signal is amplified).
Step 5: Understand that negative feedback stabilizes the gain, meaning it keeps it consistent even if conditions change.
Step 6: Realize that negative feedback also improves linearity, which means the output signal is more proportional to the input signal.
