What is Positive feedback?

Positive feedback is when something gets bigger or more intense, and that makes it even bigger or more intense again.

Imagine you're on a swing. You start swinging gently, but every time you go forward, you push yourself a little harder, and then the next swing goes higher than before. That’s positive feedback in action! Each push adds energy to your swing, making it go even higher.

Now think about a loudspeaker at a concert. If someone shouts near the microphone, the sound goes through the speaker, which makes the microphone pick up that same sound, but louder! Soon, it’s like the whole crowd is shouting all at once. That's also positive feedback, each loud sound makes the next one even louder.

Or picture a snowball rolling down a hill. At first, it's just a tiny ball of snow. But as it rolls, it picks up more snow, getting bigger and faster with every step. That’s like positive feedback too, each big snowball makes the next one even bigger!
