2. Chapter 13.1 Notes
Electric charge an electrical property of matter that creates a force between object.
Opposite charges attract
Like charge repel
Electrons 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 Notes
Electrical 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 = voltage
current
Semiconductor has properties in between conductors and insulators.

7. Chapter 13.3 Notes
Electric 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.
