What Is The Difference Between Positive And Negative Feedback

Furthermore positive feedback loops result in more products.

On the other hand negative feedback contributes to destroying self confidence. Negative feedback loops always help to maintain homeostasis whereas positive feedback usually destabilizes the systems in the body. Negative feedback paves way for losing opportunities. Negative feedback loops involve in maintaining body temperature ph ion concentration etc whereas positive feedback loops involve in blood clotting and uterus contractions in childbirth.

This is another important difference between positive and negative feedback. Positive feedback may be associated with vicious cycles and illnesses while negative feedback is closely related with maintaining good health. Positive feedback loops result in an increase in the change of the variable while negative loops result in a decrease in the change of the variable. The main difference between positive and negative feedback loops is that the positive feedback loops amplify the initiating stimulus moving the system away from its equilibrium whereas the negative feedback loops counteract the changes of the system maintaining them in a set point.

On the other hand positive feedback paves the way for gaining opportunities. The difference between a positive and negative feedback loop is in the effect the response has on the variable to be regulated. Hence do not help to maintain homeostasis more often. Unlike negative feedback positive feedback may require external interruption.
