Dielectrics: why they strengthen capacitors. Capacitors . Physics 2102. Gabriela Gonz. á. lez. Capacitors and Capacitance. Capacitor: any two conductors, one with charge +. Q. , other with charge -. Q. +Q. -Q. Uses: storing and releasing electric charge/energy. . A PowerPoint Presentation by. Paul E. Tippens, Professor of Physics. Southern Polytechnic State University. ©. 2007. Objectives: . After completing this module, you should be able to:. Calculate the . Class Activities: Conductors + Capacitors (slide 1). Class Activities: Conductors + Capacitors (slide 2). Class Activities: Conductors + Capacitors (slide 3). A point charge +q sits outside a solid . 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. Military Certificate: GJB90018-2009 (TA Cap).
