| A material in which electrons are able to move easily. | conductor |
| A material in which electrons are not able to move easily. | insulator |
| closed path through which electrons flow. | circuit |
| circuit with more than one path. | parallel circuit |
| circuit with only one path. | series circuit |
| tendency of a material to oppose electron flow | resistence |
