Electricity Terms
Mill Creek Middle Electricity terms 8th grade Science
| Question | Answer |
|---|---|
| Like charges | Charges that will repel |
| Unlike charge | Charges that will attract |
| Electric Field | The area around charged particles that exerts a force on other charged particles |
| Protons | The positively charged particle of an atom |
| Electron | The negatively charged particle of an atom |
| Static electricity | The buildup of charges on an object which do not flow |
| Friction | The transfer of electrons from one object to another by rubbing |
| Conduction | The tranfer of electrons from one object to another by direct contact |
| Induction | The movement of electrons to one part of an object caused by the electric field of another object |
| Law of conservation of charge | Electrons are not created or destroyed they are only transferred from one location to another |
| Static cling | Static electricity that causes clothes to stick together and is what enables plastic wrap to cling |
| Static discharge | The loss of static electricity as electric charges move off an object |
| Lightning | a discharge of static electricity between clouds and the earth |
| Electroscope | A device used to detect static charge |
| Potential difference | The difference in electrical potential between two places which pushes charge through a circuit |
| Voltage | Another name for the potential difference, measured by a voltmeter |
| Volt | The unit of measure for the potential difference |
| Batteries and generators | Voltage sources |
| Resistance | The opposition to the movement of electric charges flowing through a material |
| Ammeter | An instrument used to measure current |
| Amps | The unit used to measure current |
| Ohm's Law | The resistance is equal to the voltage divided by the current |
| Series circuit | An electric circuit with a single path |
| Parallel circuit | An electric circuit with multiple paths |
| Short circuit | A connection that allows current to take an unintended path. |
| Alternating current | Current consisting of charges that move back and forth in a circuit |
| Conductor | A material through which electrons move freely, forming an electric current |
| Direct current | Current consisting of charges that flow in only one direction in a circuit |
| Electric circuit | A complete path through which electric charges can flow |
| Electric current | The flow of electric charges through a material |
| Electrolyte | A liquid or paste that conducts electricity |
| Grounded | Allowing charges to flow directly from the circuit to the ground connection |
| Insulator | A material through which the charges of an electric current are not able to move |
| Step-down/step-up transformers | Devices engineered to decrease or increase voltage |
| Terminal | The part of an electrode above the surface of the electrolyte |
| Third prong | Part of a plug which connects the metal shell of an appliance to the safety grounding wire of a building |
| wet cell | An electrochemical cell in which the electrolyte is a liquid |
| dry cell | An electrochemical cell in which the electrolyte is a paste |
| Van de Graaff generator | a device which produces static electricity using a rubberband like belt |
| Lightning rod | A metal rod mounted on the roof of a building in order to protect a building |
| Fuse/ circuit breaker | Devices added to a circuit to prevent overheating |
| Ohm | The unit of measure for resistance |
