Gary From Amigos Podcast demonstrates his method of replacing capacitors in an Commodore Amiga 600. A capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. Inside a common battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can’t produce new electrons. The most commonly used and produced capacitor out there is the ceramic capacitor.
