Across
- 4. What drives electrons to move through the circuit, the more of this the higher the energy.
- 5. Energy, especially electricity, that is obtained in large quantities from a fuel source and used to operate lights,heating, and machinery
- 7. Unit of power, equivalent to one joule per second, corresponding to the rate of consumption of energy in an electric circuit where the potential difference is one volt and the current one ampere
- 11. Is a material that resists the flow of heat or electricity. It helps keep heat in or out of a space, or prevents electrical currents from passing through.
- 13. Flow of electrical charges through a conductor, measured in amperes (A). It occurs when there is a voltage difference between two points.
- 14. Energy that moves from hotter objects to cooler ones. It transfers in three main ways: conduction, convection, and radiation.
- 17. The standard unit of electrical resistance in the InternationalSystem of Units.
- 21. Total amount of electricity that flows through a conductor.
- 22. Unit of energy, it’s used to measure electrical energy, amount of heat and work. It was named after the English physicist James Prescott Joule.
- 23. Is a device that alters the voltage of a flow of electricity
- 25. A force that counteracts the flow of current. It serves as an indicator of how difficult it is for current to flow.
Down
- 1. Stands for one thousand watts.
- 2. Set of electrical elements connected to each other that allow generating, transporting and using electrical energy with the aim of transforming it into another type of energy.
- 3. Object that stores energy and uses it to power things like phones, video games or cars, without needing to be connected to electrical current.
- 6. Form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
- 8. Electrical component that can disconnect or connect the conducting path in an electrical circuit
- 9. The last letter is Z. The SI derived unit used to measure the frequency of vibrations and waves, such as sound waves and electromagnetic waves.
- 10. Small safety component in electrical devices that stops the flow of current if it's too high, preventing fires or other hazards.
- 12. something, it means you remove its electrical charge
- 15. Intensity of an electric current. In other words, it measures how much energy flows between two points for a certain period of time.
- 16. Collection of components that work together to create and distribute light.
- 18. Mechanism capable of transforming a type of energy (electrical, combustion, etc.) into mechanical energy.
- 19. Occurs when an object contains two distinct and opposite poles that can attract or repel each other
- 20. A machine that transforms mechanical energy to electric energy.
- 24. charge The charge carried by an electron.
