If someone speaks too loudly into a microphone, a public address system will sometimes produce a loud whistle of amplified feedback
Explain whether this is an example of negative or positive feedback, and explain how the microphone, control box, and speaker of the system serve as the different components of a feedback loop.
This is an example of positive feedback, where the mic is a receptor (it receives the input), the control box is a control center (it has knobs to adjust settings), and the speaker is an effector (it ultimately produces the sound).
