PPT-Capacitors II

Physics 2415 Lecture 9 Michael Fowler UVa Todays 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).

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. .
