Answer:
The given situation is an example of the <u>Positive feedback loop</u><u>.</u>
Explanation:
Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.
<u>Therefore, the given situation is an example of the </u><u>Positive feedback loop</u><u>. </u>
