Term | Definition |
---|---|
Static electricity | The accumulation of excess electric charge on an object |
Law of conservation of charge | Charge can be transferred from object to object, but it cannot be created or destroyed |
Conductor | A material in which electrons are able to move easily is a conductor. |
Insulator | A material in which electrons are not able to move easily in |
Charging by contact | The process of transferring charge by touching or rubbing. |
Charging by induction | The rearrangement of electrons on a neutral object caused by a nearby charged object. |
Electric Current | The net movement of electric charges in a single direction |
Voltage difference | related to the force that causes electric charges to flow |
Circuit | A closed path that electric current follows |
Resistance | The tendency for a material to oppose the flow of electrons, changing electrical energy into thermal energy and light. |
Ohm's law | The current in a circuit equals the voltage difference divided by resistance. |
Series circuit | The current has only one loop to flow through |
Parallel Circuit | Contain two or more branches for current to move through |
Electrical Power | The rate at which electrical energy is converted to another form of energy is the electric |
