| static electricity | the buildup of an electric charge on a material |
| discharge | the sudden movement of an electric charge from an object where it built up to another nearby object |
| conductor | a material through which heat or electricity flows easily |
| insulator | a material through which heat or electricity does not flow easily |
| circuit | a complete path through which electricity can flow |
| current electricity | a moving electrical charge |
| series circuit | a circuit in which the objects are connected in a single path |
| parallel circuit | a circuit in which each object is connected to the cell separately |
| fuse | A device that melts to keep too much electric current from flowing through wires. Once melted, a fuse cannot be reused. |
| circuit breaker | a reusable switch that protects circuits form dangerously high currents. |
| pole | one of two ends of a magnet; where a magnet's pull is strongest |
| magnetic field | a region of magnetic force around a magnet |
| electromagnet | a temporary magnet created when current flows through wire wrapped in coils around an iron bar |
| electric motor | a power source that transforms electrical energy into movement, or mechanical energy |
| generator | a device that creates alternating current by spinning an electric coil between the poles of a powerful magnet |
