PPT-Capacitors, Ammeters, & Voltmeters

Capacitors Capacitors store electrical potential energy by creating a separation of charge usually on two parallel plates Positive battery terminal pulls electrons from one plate and pushes them through . Physics 2415 Lecture 9. Michael Fowler, . UVa. Today’s Topics. First, some review… then. Storing . energy in a capacitor. How energy is stored in the electric field. Dielectrics: why they strengthen capacitors. . Capacitance:. When a capacitor is charged, its plates have charges of equal magnitudes but opposite signs: . q+ . and . q-. . However, we refer to the charge of a capacitor as being . q. , the absolute value of these charges on the plates. 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 .
