Three electrolytic capacitors with capacitance values of 2200 microfarads,1000 microfarads and 470 microfarads. The arrows on the canisters are pointing to the capacitors' negative ends. A capacitor is similar to a battery in that it is designed to store and release electrons. It has two terminals (electrodes) that connect to two metal plates separated by a dielectric (non- conducting material). However,unlike a battery,a capacitor cannot produce new electrons and must be charged. Also,a capacitor can release its charge in under a second,compared to a few minutes for a battery. This is used to power a camera flash,for example | |
