| Electric charge | Property that causes protons and electrons to attract or repel each other |
| Law of Conservation of Charges | Charge can be transferred from object to object, but it cannot be created or destroyed |
| Electric Force | The force between charged objects |
| Electric Field | Region around a charged particle where an electrical force is present |
| Conductor | Material through which electrons move easily |
| Insulator | Material in which electrons are not able to move easily |
| Friction | Rubbing objects together can cause electrons to be wiped off one substance and transferred to the other. |
| Conduction | Electrons are transferred from one charged object to another by direct contact |
| Induction | A charged object comes near an uncharged object and creates a temporary charge in it |
| Electric current | Net movement of electric charges in a single direction |
| Amps | The rate at which charge passes a given point |
| Voltage difference | The amount of energy released as a charge moves between two points |
| Resistance | The tendency of a material to resist the flow of electrons |
| Alternating Current | The charges continually switch from flowing in one direction to flowing in the reverse direction |
| Direct Current | Current always flows in the same direction |
| Circuit | A closed path through which an electric current flows |
| Load | A device that uses energy to do work |
| Switch | Opens & closes a circuit |
| Series circuit | An electric circuit with only one path for current to flow |
| Parallel circuit | An electric circuit with 2 or more branches |
| Power | The rate at which electrical energy is used to do work |
| Short circuit | When the current bypasses the load in a circuit |
| Overloaded circuit | When too much current is drawn through the circuit and it overheats |
| Fuse | Device in circuit that will melt and break the circuit before dangerous conditions exist |
| Circuit breaker | Switch that automatically opens the circuit if the current gets too high |
