What is the purpose 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 gain. Gain is how much the op-amp increases the input signal.
Step 3: Know that without feedback, the gain of an op-amp can vary a lot and may not be reliable.
Step 4: Negative feedback means taking a part of the output signal and sending it back to the input in the opposite direction.
Step 5: This feedback helps to control and stabilize the gain of the op-amp, making it more consistent.
Step 6: Negative feedback also improves linearity, which means the output signal is more proportional to the input signal.
