Energy and Change

2. - An electric circuit with only one path for the electric current to flow.
3. - An electrical device that converts electrical energy into sound energy.
4. - A device used to change the voltage of an electric current, either increasing or decreasing it.
5. - The continuous flow of electric charge through a loop or circuit.
8. - A material that does not allow electricity to flow through it easily, like rubber.
10. - A material that allows electricity to flow through it easily, like copper.
12. - An electric circuit with multiple paths for the electric current to flow.
13. - A single unit that stores chemical energy and converts it into electrical energy.
16. - The electrical force or "pressure" that pushes an electric current through a circuit.
17. - A safety measure that connects an electrical circuit to the Earth to prevent shocks or fires.

1. - An energy source that can be naturally replenished in a short amount of time, like solar or wind.
4. - A machine with blades that is spun by moving fluid, water, or wind to generate electricity.
6. - A material's opposition to the flow of electric current, slowing it down.
7. - A combination of two or more cells connected together to provide electrical energy.
9. - An energy source that exists in limited amounts and can be completely used up, like coal or oil.
11. - The measurement of electrical power, showing how much energy an appliance uses per second.
14. - Any device in a circuit that consumes electrical energy, such as a lightbulb or a buzzer.
15. - An electrical device that converts electrical energy into mechanical energy or movement.
