| Question | Answer |
|---|---|
| Energy of moving electrons or electric charges | electrical energy |
| Not easily becoming hot | heat resistant |
| The direction the electricity is moving | current |
| Electricity from a battery, solar, cell, fossil fuels or wind generator | source/cell |
| A wire that a current flows through | path |
| A safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe travel. | fuse |
| Turns a circuit on and off | switch |
| An electric current in which electrons have only one path to take. If one light goes out or removed, they all go out | series |
| A circuit where the electrons have many paths to take. If one light is removed the other lights will still work and will even get brighter. | parallel |
| A device that uses magnets to change mechanical energy into electricity | generator |
| objects appear larger and closer | convex lens |
| objects appear smaller and farther | concave lens |
| The bouncing back of light waves off a surface | reflection/reflect |
| The bending of light waves as they move through one medium into another | rafraction/refract |
