Term | Definition |
---|---|
Insulator | A material that doesn't allow electrons to flow through it easily. |
Conductor | A material that allows electrons to flow freely through it. |
Induction | The rearrangement of electrons on a neutral object, caused by a nearby charged object. |
Volt | Unit used to measure voltage. |
Ampere (Amp) | Unit used to measure current. |
Fuse | A device used to keep electrical circuits from overheating. |
Resistance | The tendency for a material to oppose the flow of electrons. |
Ohm | Unit used to measure resistance. |
Ohm's Law | The statement that current is equal to the voltage difference, divided by the resistance. |
Series Circuit | A path that allows only one route for an electric current. |
Parallel Circuit | A circuit that has two or more branches for electrons to follow. |
Static Electricity | Electric charge that has accumulated on an object. |
Electrical Power | The rate at which an electrical device converts energy from one form to another. |
Electroscope | A device that can detect the presence of a static electric charge. |
Relationship among Power, Current, and Voltage | Power(P)= Current(I) x Voltage(V) |
Calculation of Electrical Energy | Energy(E)= Power(P) x Time(T) |
Circuit Breaker | A device designed to open an overloaded circuit and prevent overheating. |
Power | The rate at which appliances consume energy. |
Kilowatt-Hours | SI unit of electrical energy |
