Negative feedback is a type of feedback circuit where the output of the circuit is used to control the input. This means that the output affects the input, creating a feedback loop.
Negative feedback is used in a variety of applications, including audio amplifiers, thermostat control, and feedback control systems. In an audio amplifier, the output of the amplifier is fed back to the input, which controls the gain of the signal. This ensures that the audio output is played at the correct volume, regardless of changes in the room's noise level.
Negative feedback circuits also help to stabilize the output of a circuit. If the input of a circuit changes, the output will also change in the same direction, thus preventing the output from going out of range. This is important in applications where the output needs to be precise, such as in audio amplifiers
