Answer 1

With a magical thing called a transistor. An electron goes through one way, and it causes 100 more electrons to go through crosswise. If you use two of them, you can make it 10000 electrons. One snowball triggers an avalanche. And that’s how the tiny electric current from the pickup makes a big electric current go through the speaker. Of course, the extra electrons come from the wall.
