| Question | Answer |
|---|---|
| allows electrons to move through it easily | conductor |
| closed path through which electons flow | circuit |
| accumulation of electric charges on an object | static electricity |
| circuit with more than one path | parallel circuit |
| tendency of a material to oppose electron flow | resistance |
| does not allow electricity to move through it easily | insulator |
| push that causes charges to move | voltage difference |
| surrounds electrical energy is changed to another energy form | electric field |
| rate at which electrical energy is changed to another energy form | electric power |
| flow of electrons through a conductor | electric current |
| circuit with only one path | series |
| unit of electrical energy | kilowatt hour |
| car battery | wet cell |
| metal rod that directs lightning to Earth | lightning rod |
| device that detects electric charges | electroscope |
| flashlight | dry cell |
| states that charge can be transferred from one object to another but cannot be created or destoryed | law of conservation of charge |
| the process of transferring charge by touching or rubbing | charging by contact |
| the rearrangement of electrons on a neutral object caused by a nearby charged object | charging by induction |
| just as for two electric charges, the forse between ant two object that are electrically charged blank as the object gets farther apart | decreases |
| carpet has became what charged | positively |
