Across
- 1. An electrical component that controls the flow of electricity by either connecting or disconnecting a circuit
- 4. A material that allows electricity or heat to flow through it easily.
- 5. Opposite poles of a magnet will __________ eac other.
- 9. The unit that measures electrical current.
- 10. A type of magnet where the magnetic field is produced by an electric current
- 12. A unit of power that measures the rate at which energy is transferred or used
- 14. The force exerted by magnets when they attract or repel each other due to the movement of electrical charges.
- 15. The flow of electrical charge (electrons) from one place to another.
- 19. An invisible region of force surrounding a magnet, electric current
- 21. A closed loop that can flow electricity.
Down
- 2. A material, typically soft iron, that acts as a magnet only while exposed to an external magnetic field or electric current
- 3. The source of energy in a circuit
- 6. A buildup of electric charge on the surface of an object, resulting from an imbalance between positive and negative charges.
- 7. Any component or device that consumes electrical energy in a circuit
- 8. A measure of how much material opposes the flow of electric current. Measured in Ohms
- 11. A type of electrical circuit with multiple paths for current to flow.
- 13. A type of circuit where all of the components are arranged in a single path.
- 16. A material that does not easily allow heat, electricity, or sound to pass through it.
- 17. To force something to move apart.
- 18. Measures how much “pressure” there is in an electric circuit.
- 20. The flow of electrons through a conductor. Measured in Amps.
