Negative Feedback, also known as "inverse feedback," is a type of feedback mechanism in which the output of a system is used to decrease or regulate the input. The output is compared to a target or set point, and any deviation from that target is used to adjust the input in such a way as to reduce the deviation and bring the output back to the target.Negative feedback is commonly used in control systems, such as thermostats, to keep temperatures constant.For example, a thermostat uses negative feedback to adjust the heating or cooling system in a building. If the temperature in the building is too high, the thermostat sends a signal to the heating or cooling system to decrease the temperature. Once the temperature is lowered to the set point, the thermostat stops sending the signal, and the temperature is maintained at the set point.Negative feedback can also be seen in biological systems. For example, the human body uses negative feedback to regulate hormone levels. If the level of a hormone is too high or too low, the body will release or stop releasing a different hormone to bring the level back to normal.Negative feedback can also be applied in the field of economics and business. For example, the Federal Reserve uses monetary policy to control inflation and stabilize the economy, which is a negative feedback loop.In summary, negative feedback is a mechanism that helps to keep a system in balance by adjusting the input based on the output, allowing the system to reach a steady state or equilibrium.
