Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
Negative feedback is a corrective mechanism in biological systems where the response to a stimulus results in the inhibition of that stimulus. It helps to maintain homeostasis by counteracting any deviations from the set point. For example, in the regulation of body temperature, negative feedback helps to prevent overheating or hypothermia by signaling the body to either produce more or less heat.
This phenomenon is known as negative feedback. Negative feedback occurs when the removal of a stimulus results in a decrease in the response, ultimately helping to maintain homeostasis within a system. It is a regulatory mechanism that acts to counteract any deviations from a set point.
Negative feedback maintains homeostasis by reversing any deviation from a set point. When an internal condition deviates from the stable state, negative feedback mechanisms work to dampen or counteract the change, bringing the system back to equilibrium. This process inherently "negates" or "opposes" the initial deviation, hence the term "negative feedback."
A negative feedback system is a process where the output of a system is fed back into the system as an input, which then results in a reduction or reversal of the initial output. This regulatory mechanism helps maintain stability and homeostasis in biological systems by counteracting deviations from a set point. An example is the regulation of body temperature where heat loss or gain triggers responses to bring temperature back to a normal range.
Oxygen loading is a positive feedback process where increased oxygen levels in the blood stimulate further loading of oxygen onto hemoglobin molecules. This results in more efficient oxygen transport to tissues. Negative feedback processes, on the other hand, involve a response to reduce or counteract a stimulus, aiming to maintain homeostasis.
Negative feedback is where increase in a process results in another acting to bring it back to normal. An example is in the control of blood sugar. After a meal there is a large increase in blood sugar, this results in the body producing more insulin. The insulin causes the blood sugar to be converted to glycogen which is stored in the liver and muscles and a fall in blood sugar. If one does not eat for a long time the blood sugar begins to fall. Less insulin is produced and glycogen is converted to sugar to maintain a normal sugar level. This is negative feedback
Extrinsic regulation
Its a negative feedback,because the smaller the lumen , the higher the blood pressure because of the deposit in the vessel thus causing the resistance.

In a positive feedback control system, the output enhances or amplifies the input, leading to an increase in the original signal. In contrast, a negative feedback control system reduces the output in response to deviations from a set point, helping to maintain stability and regulate the system.
