Across
- 3. One of the four fundamental forces of nature. It is the force between charged particles and is responsible for electricity, magnetism, and light.
- 5. The opposition to the flow of electric current. Materials with high resistance make it harder for electricity to pass through.
- 8. The buildup of electric charges on the surface of an object. It stays in one place until it’s released, like when you get a small shock after walking on carpet.
- 12. A device that converts mechanical energy (like spinning) into electrical energy, often using magnets and coils of wire.
Down
- 1. The force of attraction or repulsion between magnets or magnetic materials, like how opposite poles attract and like poles repel.
- 2. The flow of electric charge (usually electrons) through a material, like a wire.
- 4. A closed loop or path that electricity flows through. It usually includes a power source, wires, and devices like bulbs or switches.
- 6. The amount of electrical potential energy that pushes electric charges through a circuit. It’s often called the “pressure” of electricity.
- 7. The area around a charged object where it can exert a force on other charged objects. You can think of it as an invisible “zone of influence.”
- 9. A type of electrical current that flows in only one direction, like the electricity from batteries.
- 10. A type of electrical current that changes direction periodically. This is the kind of electricity used in homes.
- 11. The invisible region around a magnet where magnetic forces can be detected. It shows where magnetic force is acting.
