![]() See also Individual Sports - Concept and Examples Homeostasis Sweat is a negative feedback that favors homeostasis. They are very common in electrical power supplies. How the capacity multipliers work, which are transistors configured to multiply the capacity of a capacitor, gaining current as it travels through the circuit.Sound feedbackAn unpleasant noise characteristic of misplaced microphones in a recording, it occurs when the audio signal emitted by the speakers is captured by the microphone and emitted again, amplifying the sound until it becomes noise.If the latter is used to improve the facilities, it will be possible to fish more efficiently, increasing the money obtained and so on. A fishing facility it extracts a certain quantity of food from the sea, with which it pays for its maintenance and obtains a surplus.When conducting a greater electrical charge, an increase in temperature is produced, which allows the charge to increase and so on, until the artifact is destroyed if no other process intervenes. How semiconductors work, whose ability to conduct electricity is greater the higher its temperature.Medical exams who draw our blood to see how healthy we are and with that information modify our diet or our lifestyle.A user satisfaction survey, provided by a company to its clientele so that they can return to the company the information they consider about the operation of the same.The dynamics of teaching evaluation They serve to control how well the teaching dynamics works, since the class provides the teacher with the necessary information about the learning that takes place in it, and allows him to make adjustments in it.The refrigerator thermostat, which measures the temperature continuously, and once the desired minimum is reached, it turns off the compressors and stops cooling and once the maximum allowed is reached, it turns them on again. ![]() See also Realism - Concept, types, characteristics and representatives Having understood the difference between positive and negative feedback, we can find other examples for each: See also: Interdependence Examples of positive and negative feedback An example of this is the reinvestment of capital from a factory, in which the money obtained from the sale of products is spent on new machines that allow more products to be manufactured, in order to obtain more money and be able to improve the machines again. That is, it tends to increase the signal or activity, since by returning the information at the beginning, it enhances certain changes in the process. Positive feedback has a creative, productive, and change-pushing effect.This is what happens, for example, with the quality control systems of factories: a portion of the manufactured products do not go on sale, but are consumed internally to ensure that they meet minimum quality standards. It returns the information produced to the issuer, so that it can correct the input pattern, and thus keeps the system working. Negative feedback has a stabilizing effect on the system.This hormone stimulates the production of red blood cells.That is, the two possible types of feedback lead to different scenarios: ![]() Production of human red blood cells ( erythropoiesis) - A decrease in oxygen is detected by the kidneys and they secrete erythropoietin.Some is stored as body fat, and other glucose is stored as glycogen in the liver and muscles. Regulation of blood sugar in humans - When blood sugar rises, insulin sends a signal to the liver, muscles, and other cells to store the excess glucose.Human metabolism - When a human is hungry, metabolism slows down to conserve energy and allows the human to continue living with less food.Signals are sent to the heart from the brain, and heart rate slows down, thus helping blood pressure to return to normal. Human blood pressure - When blood pressure increases, signals are sent to the brain from the blood vessels. ![]() If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.
