PPT-Batteries & Capacitors

And How They Work What are the ways we store electricity What are some objects that require batteries that you use Battery History The first battery was created by Alessandro Volta in 1798 Volta was an Italian professor in physics and chemistry . Capacitance. Capacitance is the ability of a dielectric (insulator) to store an electrical charge. Demo a large capacitor being charged and discharged. Charge = Coulomb = Q = 6.25 X 10. 18. electrons. ECB 3211 – RF & Microwave Engineering. Module - I. SOURCE: RF & Microwave Handbook, CRC Press. 1. Lumped Components. Lumped components provide . impedance matching. , attenuation, filtering, DC bypassing, and DC . Dr. John Warner. December 15, . 2017. Introduction. Electricity is inherently mysterious. We do not have a sense to detect its presence. Sight – detects light. Hearing – detects sound. Smell – detects chemical vapors. What is a capacitor?. A . capacitor. can be formed from any ungrounded conductor or pair of conductors.. A very common capacitor is made from . two parallel plates . of metal.. Charging a capacitor . Magic of Electrons . Capacitors. Capacitors. Charging the Capacitor. Discharging the Capacitor. This presentation is intended to be used with Activity 6.2.5 Capacitors.. Capacitors. Capacitor:. .

Uses: storing and releasing electric charge/energy. . resistors. A resistor, like batteries and lights, can also be present in an electrical circuit. A resistor limits the flow of electricity in the circuit. Like rocks in a pipe that slow the flow of water, a resistor will limit the flow of electricity. A variable resistor is made of a piece of metal that can change in length. As the length of the resistor changes, so does the resistance in the same direction. . Battery- combination on 2 or more electrochemical cells that convert chemical energy into electrical energy.. Luigi Galvini and Allesandro Volta are credited with the invention of the first batteries..
