Science study notes Unit 3 Vocabulary Coulomb: metric unit for electrical charge Conduction: movement or transmission of electrons through a substance Induction: can create temporary or permanent charges Static: “static” in terms of “static electricity” means that the charges will remain very, nearly fixed in one place on the surface of an object until they are given a path to escape Electron affinity: an atom’s tendency to hold onto electrons Electrical insulators: solids, liquids or gases that resists or blocks the movement of electrons Current electricity: movement, conductors and a substance that allows for easy movement of electrons, has continuous flow of electrons Electricity: energy carried be electrons Electroscope: detects static charge Grounding: connecting a charged object to the Earth’s surface Lighting rod: redirects the electrical strike away from the building Insulated wire: Allows the electrical strike to move away from the house Ground rod: allows strike to lose it’s charge Electric circuit: a complete path for electrons to flow Electrolyte: a liquid or paste that conducts electricity Electrode: a metal strip that reacts with an electrolyte Potential difference: measure the difference in electric potential energy between 2 points, measured in volts Electric current: a measure of the amount of electric charge that passes by a point in an electrical circuit each second, measured in amperes Resistance: when a substance opposes the flow of electric current, measured in Ohms Electrical efficiency: comparison between the useful energy( energy used to produce desired results) and the total energy input Friction: a force being applied, resisting the relative motion of two different surfaces upon contact Electron affinity: tendency of a substance to hold electrons Energy: a quantity,
