is a capacitor a battery
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals.Inside the 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 -- it only stores them.In this article, we'll learn exactly what a capacitor is, what it does and how it's used in electronics. We'll also look at the history of the capacitor and how several people helped shape its progress. capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them.
