A negative F/B applies as applied to electronics systems meas that a portion of the output signal will be fed back to stabilize the system. It must be negative in nature so as to control the stability of the loop. If positive F/B is fed back then an uncontrollable situation will occurs whereby the system will oscillate uncontrollably As a rule the more negative F/B is applied the more stable the system. Also as a rule the more F/B the less gain is available to do work. So there is a trade off as stability increased the overall gain decreases.
Q: describe the negative- feedback system subject: Science A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system. example: it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream. ur wlcm (: SnazzyChazzy <33
Mechanical confusion is a term used to describe a lack of clarity or understanding about how a mechanical system works or how different parts interact with each other. It refers to a state of uncertainty or disorientation regarding the functioning of machinery or equipment.

A microwave oven works as a closed-loop system by constantly monitoring and adjusting the temperature inside the oven using sensors and a control unit. If the temperature deviates from the set value, the control unit adjusts the power output of the microwave generator to maintain the desired temperature. This continuous feedback loop ensures that the food is heated evenly and efficiently.
The field of study that includes several laws that describe how energy transfer works is physics. Some important laws related to energy transfer in physics include the laws of thermodynamics, the conservation of energy, and the various laws governing specific types of energy transfer, such as Ohm's law for electrical energy transfer.
it compares the output with the input and adjusts it self to match with it.
The main characteristic of negative feedback is that it works to counteract or reduce a change in a system, maintaining balance or stability. It acts to reverse the direction of the change, helping to regulate and maintain homeostasis.

The main characteristic of a negative feedback mechanism is that it works to maintain homeostasis by counteracting changes in a system. When a parameter deviates from its set point, the mechanism activates to bring the parameter back to its normal range, thus stabilizing the system.
To remove the distortion ... ANSWER: It does not reduce distortion but rather make the circuit stable. There can be distortion even with negative feedback by bad design in other word feedback does not reduce distortion.
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
A negative feedback loop works to counteract changes in a variable, promoting stability within a system. When an initial change occurs, the negative feedback mechanism detects this deviation and triggers responses that reduce or negate the change. For example, if a body temperature rises, mechanisms like sweating are activated to lower it back to the set point. Thus, the negative feedback loop effectively dampens the initial change, restoring equilibrium.
Negative feedback is a process that happens when your systems need to slow down or completely stop a process that is happening. When you eat, food travels into your stomach, and digestion begins. You don't need your stomach working if you aren't eating. The digestive system works with a series of hormones and nervous impulses to stop and start the secretion of acids in your stomach. Another example of negative feedback occurs when your body's temperature begins to rise and a negative feedback response works to counteract and stop the rise in temperature. Sweating is a good example of negative feedback.
Atrial natriuretic peptide (ANP) works as a negative feedback to aldosterone. ANP is released from the atria of the heart in response to high blood volume and works to decrease sodium reabsorption in the kidneys, opposing the actions of aldosterone.
No, homeostasis can also be achieved through positive feedback systems. Negative feedback works to maintain stability by reversing any deviations from a set point, while positive feedback enhances or amplifies changes in a system to facilitate a specific outcome. Both types of feedback mechanisms play crucial roles in maintaining balance in biological processes.
Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment
