Production by modification or improvement: It involves change in chemical and mechanical parameters of the raw material without altering physical attributes of the raw material. Annealing process (heating at high temperatures and then cooling), is example of production by modification or improvement.
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.

What you need to learn yet is how the capacitor is used in a circuit-what it does when you use it. That's the topic of the next section. If you can learn that then you can begin to learn some of the things that you can do with a capacitor. Capacitors are a very interesting kind of component. Be able to write and use the voltage-current relationship for the capacitor, 2  Be able to compute the current through a capacitor when you know the voltage across a capacitor. 3  Given a capacitor that is charged, 4  Be able to compute the amount of energy that is stored in the capacitor.
