PPT-Chap-25: Capacitance Capacitor:

Capacitor is a device in which electrical energy can be stored Ex Photoflash in a camera The physics of capacitors can be generalized to other devices and to any situation involving electric fields . 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!. 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. Capacitors and Dielectrics. Conductors are commonly used as places to store charge. You can’t just “create” some positive charge somewhere, you have to have corresponding negative charge somewhere else. Unit 8: Capacitors. Today’s Concept:. Capacitors in a circuits . Dielectrics.
