lesson 2
| Term | Definition |
|---|---|
| How is electric current made? | when electric charges are made to flow through a material they provide an electric curent |
| Electric Current | the contentious flow of electric charges through a material |
| what is electric current measured in? | Amperes or amps or a |
| Electric Circuit | a compete, unbroken path that charges can flow through |
| How do conductors differ from insulators? | the atoms in conductors have loosely bound electrons that can move freely. electrons in insulators cannot move freely among atoms |
| Conductor | a material through which charges can flow easily |
| Insulator | a material such as rubber, that do not allow charges to flow through |
| What affects current flow? | current flow is effected by energy of the properties of the objects that charges flow through |
| Voltage | the difference in electric potential energy per charge between two points in a circuit |
| Resistance | the measure of how different it is for charges to flow through an object |
| The more resistance = | less current |
| What are the 4 factors that determine Resistance? | diameter, length, material, and temperature |
