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