What is the effect of positive feedback on stability of the system?
Positive feedback occurs in a feedback loop when the effects of a small disturbance on a system include an increase in the magnitude of the perturbation, Basically, it is when ‘A produces more of B which in turn produces more of A’
Positive feedback tends to lead to instability. It promotes exponential growth, oscillation or chaotic behavior. Negative feedback, on the other hand, generally promotes stability.
