19.5 Capacitors and Dielectrics

A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.13. (Most of the time an insulator is used between the two …

B8: Capacitors, Dielectrics, and Energy in Capacitors

Moving charge from one initially-neutral capacitor plate to the other is called charging the capacitor. When you charge a capacitor, you are storing energy in that capacitor. Providing a conducting path for the charge to go back to the plate it came from is called discharging the capacitor. If you discharge the capacitor through an electric ...

How to determine a capacitor value across a switch carrying DC

You want to be sure the capacitor can absorb all the inductive stored energy, while staying below the rated voltage. For simple resistive loads, your only stored energy is in cable inductance, so a few nanofarads will be enough. So for a 10 A switch switching 250 V, R=12 ohms, C = 100 nF should be fine.
