Electricity CW 2
Across
- 2. the flow of electrical charge.
- 6. transfer of thermal energy from one material to another by electromagnetic waves
- 8. A type of circuit in which all the components are in a chain so that the current has only one path to take.
- 9. Materials that electricity can easily flow through (e.g., metals).
- 11. Materials that electricity cannot easily flow through (e.g., wood, plastic, rubber).
- 12. type of energy resource that is replaced as fast as, or faster than, it is used
- 13. a circuit that has a break that prevents the flow of current.
- 14. Component of a circuit that reduces the amount of electricity flowing through it.
- 16. movement of thermal energy from a warmer object to a cooler object
- 17. ability to cause change
- 19. Path that can allow electricity to flow, if closed.
- 20. type of energy resource that is used faster than it is replaced
- 22. A type of circuit in which the components are connected in parallel to each other; each component has its own separate branch.
- 23. transfer of thermal energy by the movement of particles from one part of a material to another
- 24. Measure of potential energy between two points in a circuit or in a battery.
Down
- 1. a safety device that melts when current is too high, breaking a circuit.
- 2. transfer of thermal energy between materials because of collisions between particles
- 3. A variable resistor that is a component of a circuit that can control the amount of electricity flowing through it using a knob or a slider.
- 4. A device that stores electrical energy.
- 5. nonrenewable energy resources made of the remains of ancient organisms and is burned as an energy source
- 7. force that resists the motion of two surfaces that are touching
- 9. circuit a circuit that has a complete path for charge to flow.
- 10. energy that is stored in the nucleus of an atom
- 11. type of energy resource that cannot be used up
- 15. an unwanted electrical connection with very low resistance to current.
- 18. Flow of electrical energy from one place to another.
- 21. A component of a circuit that regulates the flow of electricity (can amplify the signal).
