Term | Definition |
---|---|
Static Electricity | The accumulation of excess electric charge on an object. |
Law of Conservation of Change | States that charge can be transferred from object to object, but it cannot be created or destroyed. |
Electric Field | Surrounds every electric charge and exerts the force that causes other electric charges to be attracted or repelled. |
Conductor | A material through which electrons move easily. |
Insulator | A material in which electrons are not able to move easily. |
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. |
Electroscope | A device that can detect electric charge. |
Electric Current | The net movement of electric charges in a single direction. |
Voltage Difference | Related to the force that causes electric charges to flow. |
Electric Circuit | A closed path that electric current follows. |
Resistance | The tendency for a material to resist the flow of electrons and to convert electrical energy into other forms of energy, such as thermal energy. |
Ohm's Law | The current in a circuit equals the voltage difference divided by the resistance. |
Series Circuit | An electric circuit with only one branch. |
Parallel Circuit | Contain two or more branches for current. |
Electrical Power | The rate at which electrical energy is converted to another form of energy. |
