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. |
conductor | A material in which electrons are able to 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 induciton | 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 | is related to the force that causes electrical charges to flow. |
circuit | A closed path that electric current follows. |
resistance | is the tendency for a material to oppose the flow of electrons,changing electrical energy into thermal energy and light. |
Ohms law | the current in a circuit equals the voltage difference divided by the resistance. |
series circuit | The current has only one loop to flow through. |
Parallel circuit | contain 2 or more branches for current to move through. |
electric power | The rate at which electrical energy is converted to another form of energy. |
