Positive feedback is used in digital electronics to force voltages away from intermediate voltages into '0' and '1' states. On the other hand, thermal runaway is a type of positive feedback that can destroy semiconductor junctions. Positive feedback in chemical reactions can increase the rate of reactions, and in some cases can lead to explosions.
Positive feedback occurs when the fed-back signal is in phase with the input signal. Under certain gain conditions, positive feedback reinforces the input signal to the point where the output of the device oscillates between its maximum and minimum possible states. Positive feedback may also introduce hysteresis into a circuit. This can cause ...
Wikipedia should have methods of positive feedback to allow both incentives for improvement and polite and civil interactions. Wikipedia should help people more than it hurts them (Wikipedia:Avoiding harm). Wikipedia should have verifiable civility, and it should have measures to avoid turnover.

The Thanks notification offers a way to give positive feedback on Wikipedia. This feature allows editors to send a "thank you" notification to users who make useful edits – by using a small "thank" link on the history page or diff page.
For example, social media, such as Facebook, users risk criticism by posting a diary, but the majority of Facebook users receive a majority of positive feedback. Wikipedia, however, does not allow socializing on article talk pages, which should be used mainly or entirely to discussions regarding improving articles.
Audio feedback, the "howl" sometimes heard in microphone or guitar amplification systems; Video feedback, the optical equivalent of audio feedback, caused when a camera films the image it is producing; Positive feedback, a feedback system that responds to perturbation in the same direction as the perturbation
English: The diagram demonstrates positive feedback, using the example of blood clotting in the body. The damaged blood vessel wall releases chemicals that initiate the formation of a blood clot. The damaged blood vessel wall releases chemicals that initiate the formation of a blood clot.
