Across
- 2. circuit Needs 3 things to give energy:1. energy source (battery or wall socket)2. energy receiver (wall socket), 3. energy pathway or circuit (wire)
- 3. the electricity flows in one current (from batteries, fuel cells & solar cells)
- 4. electricity The result of electrons being pulled from one place to another, excess buildup
- 7. machines that change mechanical energy (wind, water, fossil fuels) into electrical energy to make an alternating current (AC)
- 9. current a path that electrons can flow through (to give power)
- 10. A steady flow of electrons
Down
- 1. A form of energy caused by the movement of electrons
- 5. power plants give it energy so that voltage can be increased or decreased
- 6. material that allows electrons to flow through it easily (ex. metals)
- 8. the current flows in one direction, then changes to a different direction
