PPT-Capacitance and Dielectrics

AP Physics C Capacitors A capacitor consists of 2 conductors of any shape placed near one another without touching It is common to fill up the region between these 2 conductors with an insulating material called a dielectric. AP Physics C. Applications of Electric Potential. Is there any way we can use a set of plates with an electric field? . YES!. We can make what is called a Parallel Plate Capacitor and Store Charges between the plates!. 5.1 Introduction A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5 Chapter 24 What is Capacitance? • Capacitance (C) is equal to the Charge (Q ) between two charges or charged “regions” divided by the Voltage (V) in those regions͘  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.

Dielectric materials are also called as insulators.. In dielectric materials, all the electrons are tightly bound to their parent molecules and there are no free charges.. Module 1I. Conduction and Breakdown in Liquid Dielectrics . Department of Electrical Engineering. Liquid dielectrics are used mainly in high-voltage cables and capacitors and for filling up of transformers, circuit breakers, etc..
