A: A capacitor, or cap, is an electronic component that can take up, store, and discharge electrical energy. Because they can do all that quickly, capacitors are used to filter or buffer any sudden changes in a circuit's voltage, smoothing the ensuing signal.back to top.: A capacitor, or cap, is an electronic component that can take up, store, and discharge electrical energy.

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.
