Define And explain Capacitor??
Answers
Answer:
A capacitor is a passive electronic component that stores energy in the form of an electrostatic field. In its simplest form, a capacitor consists of two conducting plates separated by an insulating material called the dielectric.
Answer:
One goal of physics is to provide the basic science for practical devices designed by engineers. The capacitor, a device in which electrical energy can be stored. For example, the batteries in a camera store energy in the photo flash unit by charging a capacitor. The batteries can supply energy at only a modest rate, too slowly for the photo flash unit to emit a flash of light. However, once the capacitor is charged, it can supply energy at a much greater rate when the photo flash unit is triggered—enough energy to allow the unit to emit a burst of bright light.
The physics of capacitors can be generalized to other devices and to any situation involving electric fields. For example, Earth’s atmospheric electric field is modeled by meteorologists as being produced by a huge spherical capacitor that partially discharges via lightning. The charge that skis collect as they slide along snow can be modeled as being stored in a capacitor that frequently discharges as sparks (which can be seen by nighttime skiers on dry snow).
