Question | Answer |
---|---|
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 induction | the rearrangement of electrons on a neural 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 |
ohm's 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 | two or more branches for current to move thorugh |
electrical power | the rate at which electrical energy is converted to another from of energy |
