| Got it wrong? Go study!! | Definition |
|---|---|
| Law of Electric Charges | the law that states that like charges repel and opposite charges attract |
| 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 |
| Electrical Conductor | a material in which charges can move freely |
| Electrical Insulator | a material in which charges cannot move freely |
| Static Electricity | electric charge at rest; generally produced by friction or induction |
| Electric Discharge | the release of electricity stored in a source |
| Electric Current | the rate at which charges pass through a given point; measured in amperes |
| Voltage | the potential difference between two points; measured in volts |
| Resistance | in physical science, the opposition presented to the current by a material or device |
| Cell | in physics, in electricity, a device that produces an electric current by converting chemical or radiant energy into electrical energy |
| Thermocouple | a device that converts thermal energy into electrical energy |
| Photocell | a device that converts light energy into electrical energy |
| Electric Power | the rate at which electrical energy is converted into other forms of energy |
| 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 such that the potential difference across each part is the same |
| 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 |
| Electromagnetism | the interaction between electricity and magnetism |
| Solenoid | a coil of wire with an electric current in it |
| Electromagnet | a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil |
| Electric Motor | a device that converts electrical energy into mechanical energy |
| Electromagnetic Induction | the process of creating a current in a circuit by changing a magnetic field |
| Electric Generator | a device that converts mechanical energy into electrical energy |
| Transformer | a device that increases or decreases the voltage of alternating current |
