| Electric Charge | An electric property of matter that creates electric and magnetic forces |
| Coulomb | The unit used to measure electric charge |
| Electrical conductor | materials that allow charges to move freely through them. |
| Electrical insulator | Materials that do not allow charges to move freely through them. |
| Charge by contact | When a charged object touches a neutral object, causing it to also become charged. |
| Charge by friction | When two materials are rubbed together; one material becomes positive while the other becomes negative. |
| Charge by induction | When the positions of electrons change within molecules or objects due to another charged object being near, but not touching. |
| Electric force | The force of attraction or repulsion on a charged particle that is due to an electric field. |
| Electric Field | The space around a charged object in which another charged object experiences an electric force. |
| Potential Difference | The voltage difference in potential between two points in a circuit. Causes charges to move. |
| Electric Current | The rate at which charges move through a wire |
| Ampere | The SI unit of current |
| Voltage | The SI unit of Potential Difference |
| Resistance | The opposition presented to current by a material or a device, such as a lightbulb. This is caused by internal friction. |
| Ohm's Law | Describes the relationship between voltage, current, and resistance. |
| Electric Circuit | A set of electrical components connected so that they provide one or more complete paths for the movement of charges from one end of a battery to the next. |
| Schematic Diagram | A graphical representation of a circuit that uses lines to represent wires and different symbols to represent parts of a circuit. |
| Series Circuit | A circuit in which the parts are joined one after another such that the current in each part is the same. |
| Parallel Circuit | A circuit in which the parts are joined in branches so that the voltage across each part is the same. |
| Path of Least Resistance | Describes how most charges in a parallel circuit will run through the path that has the smallest opposition to current. |
| Watt | The SI Unit used to describe power |
| Kilowatt | A Unit used to describe power. |
| kilowatt-hour | The unit of energy that power companies use to track consumption of energy. |
| Electric Power | The rate at which electrical energy is converted into other forms of energy. |
| Fuse | A ribbon of wire that has a low melting point. Opens a circuit when a high current causes the ribbon to melt. |
| Circuit Breaker | A switch that opens a circuit automatically when current exceeds a certain value. |
