Answer:
Positive feedback loop.
Step-by-step explanation:
Positive feedback loops: It is described as a feedback loop that is responsible for the increase changes in the system. These changes cause the system to move away from its actual equilibrium state and make it a more unsettled state in a system. So, it refers to the positive loop gain about the closed-loop of the cause and effect.
This feedback loop is defined as in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude.
