| electric circuit | 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 |
| series | a circuit or portion of a circuit that provides a single conducting path |
| parallel | components in a circuit that are connected across common points, providing two or more separate conducting paths |
| electrical energy | the energy associated with electrical charges, whether moving or at rest |
| fuse | electrical device containing a metal strip that melts when current in the circuit becomes too great |
| circuit breaker | device that protects a circuit from current overloads |
| magnetic pole | area of a magnet where the magnetic force appears to be the strongest |
| magnetic field | region where a magnetic force can be detected |
| solenoid | long, wound coil of insulated wire |
| electromagnet | strong magnet created when an iron core is inserted into the center of a current-carrying solenoid |
| electromagnetic induction | production of a current in a conducting circuit by a change in the strength, position, or orientation of an external magnetic field |
