2 Chapter 13.1 NotesElectric charge an electrical property of matter that creates a force between object.Opposite charges attractLike charge repelElectrons negative charge (-)Protons positive charge (+)Neutrons no charge (0)
3 Conductor a material that transfers charge easily. Insulator a material that does not transfer charge easily.Electric force the force of attraction or repulsion between objects due to charge.
4 Electric Field the region around a charged objects experience an electric force.
5 Chapter 13.2 NotesElectrical Potential Energy is potential energy of a charged object due to its position in an electric field.Potential difference the change in the electrical potential energy per unit charge.Cell a device that is a source of electrical current because of a potential difference, or voltage, between the terminals.
6 Current the rate that electric charges move through a conductor. Resistance the ratio of the voltage across a conductor to the current it carries.Resistance = voltagecurrentSemiconductor has properties in between conductors and insulators.
7 Chapter 13.3 NotesElectric circuit an electrical device connected so that it provides one or more complete paths for the movement of charges.Schematic diagram a graphic representation of an electric circuit or apparatus, with standard symbols for the electrical devices.
8 Series describe a circuit or portion of a circuit that provides a single conducting path. Parallel describes components in a circuit that are connected across common points, providing two or more separate conducting paths.Power = Current X Voltage
9 Electrical energy the energy associated with electrical charges, whether moving or at rest. Fuse an electrical device containing a metal strip that melts when current in the circuit becomes too great.Circuit breaker a device that protects a circuit from current overloads.
