Capacitor TechnologyGreat energy Storage in Small Place Amaris “J.W.” Jones-Wiggins Dr. Rebman
Photogenic • Where do cameras get their flash? • Capacitors take in energy • Release it in an Instant Flash!!
What’s a Capacitor? • An object that stores energy and releases it quickly • Similar to batteries except cannot create energy
Composition • Two plates inside a cell that are parts of two terminals • Plates separated by a non-conducting substance
How do Capacitors Work • Capacitors take in electrons from the charge created by the main power source and stores them • Once power has faded the capacitor picks and begins to discharge the power to continue the flow.
Storage Capacity • The Storage Capacity of a Capacitor is called a Farad. • Farad Storing capacitors are large, usually capacity is measured in microfarads *Charge assumed at 1 volt.
Functionality • Capacitors are mainly used for quick bursts of energy • Evening out uneven energy flow • Can’t store nearly as much energy as a battery.
Capacitive Technology Uses • Clock, Timers, other time keeping Devices • Wave based Devices, X-rays, MRIs, and Antennas • Cell Phones • Touch Screens
History of Capacitor • Messy Records give Credit to two People: • 1. Ewald Georg von Kleist • 2. Pieter van Musschenbroek : Invented the Leyden Jar • Concepts Expanded by Ben Franklin, and later Michael Faradey
Future of Capacitive Technology. • NanoTube Capacitors. • Greatly Increases Power for small spaces • Growing capacitors
BE CAREFUL! • Capacitors can Discharge Large amounts of power very quickly • http://www.youtube.com/watch?v=_WheLp0RdLQ&NR=1 • http://electronics.howstuffworks.com/capacitor.htm
