Across
- 2. Man's best friend
- 4. Energy from the Sun, captured using solar panels or other devices to create electricity or heat.
- 6. Has a trunk
- 10. A material that does not allow electricity to flow through it easily, like rubber or plastic.
- 12. A device that stores electrical energy and provides it to a circuit as voltage.
- 15. A unit used to measure voltage, or the force that moves electric current.
- 17. How well a device converts electrical energy into useful work, without wasting energy as heat or other forms.
- 18. Energy generated by using water flow (usually from a dam or river) to turn turbines and produce electricity.
- 19. Energy produced by the movement of air (wind), which is captured by wind turbines to generate electricity.
- 20. A unit used to measure the amount of electric current flowing in a circuit.
- 22. Likes to chase mice
- 24. A material that allows electricity to flow through it easily, like metals (e.g., copper).
- 25. A material that can conduct electricity with no resistance at very low temperatures, meaning no energy is lost as heat.
- 27. Energy from sources that cannot be replaced once used up, like coal, oil, or natural gas.
- 28. A component in a circuit that limits or controls the flow of electric current.
- 30. Energy from organic materials like plants or animal waste, which can be burned to create electricity or heat.
- 31. A device used to open or close a circuit, turning the flow of electricity on or off.
- 33. A type of circuit where the components are connected in multiple paths, so the current can flow through more than one path at the same time.
- 34. Point A place in an electrical circuit where two or more wires or components meet.
- 35. An instrument used to measure the electric current in a circuit, usually in amperes (A).
- 36. Flying mammal
- 37. A rule that says the current in a circuit equals the voltage divided by the resistance. (V = I × R)
Down
- 1. Fuel made from the remains of ancient plants and animals, like coal, oil, and natural gas. These are non-renewable.
- 3. Energy from the heat inside the Earth, often used for heating or generating electricity.
- 5. Large marsupial that hops
- 7. An instrument used to measure the voltage (electric pressure) across two points in a circuit, usually in volts (V).
- 8. The flow of electric charge (like the flow of water through a pipe), usually measured in amperes (A).
- 9. Energy produced by splitting atoms in a process called fission, which releases a lot of energy.
- 11. A material that can conduct electricity under some conditions but not others, like silicon in computers. It is somewhere between a conductor and an insulator.
- 13. A measure of how much a material or object resists the flow of electricity, like a narrow pipe that slows down water.
- 14. A type of circuit where all the components are connected one after another, so the current flows through each component.
- 16. Energy produced from the movement of ocean tides, often used to turn turbines and generate electricity.
- 21. The electric "pressure" that pushes the electric current through a circuit, measured in volts (V).
- 23. A simplified drawing of an electrical circuit, showing how all the components are connected.
- 26. Energy from sources that can be replenished naturally, like sunlight, wind, or water.
- 29. A unit used to measure electrical resistance, showing how difficult it is for electricity to flow through a material.
- 32. A unit of power, measuring the rate at which electrical energy is used or produced.
- 33. The amount of energy used or produced by an electrical device, measured in watts (W).
