Term | Definition |

Electric Charge | A fundamental property that leads to the electromagnetic interactions among particles that make up matter. |
Static Electricity | Electric charge at rest; produced by friction or induction. |
Electrical Conductor | A material in which charges can move freely. |
Electrical Insulator | A material in which charges cannot move freely. |
Semicondictor | An element or compound that conducts electric current better than an insulator does but not as well as a conductor does. |
Electric Current | The rate at which electric charges pass a given point. |
Resistance | In physical science, the opposition presented to the current by a material or device. |
Voltage | The amount of work to move a unit electric charge between two points; expressed in volts. |
Electric Circuit | A set of electrical components connected such that they provide one or more complete paths for the movement of charges. |
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 | The energy that an object has because of the position, condition, or chemical composition of the object. |
Magnet | Any material that attracts iron or materials containing iron . |
Magnetic Pole | One of two points, such as the ends of a magnet, that have opposing magnetic qualities. |
Magnetic Force | The force of attraction or repulsion generated by moving or spinning electric charges. |
Magnetic Field | A region where a magnetic force can be detected. |
Electromagnetism | The interaction between electricity and magnetism. |
Electromagnetic | A coil that has a soft iron core and that acts as a magnet when an electric current is in the coil. |
