  1. 2. "____ electron": Needed for electricity to work
  2. 4. - There are many free electrons in this material
  3. 6. A type of electricity where charges build up on surfaces
  4. 7. When components are connected on the same loop
  5. 10. The unit that is used to measure current
  6. 11. - In this material, electrons struggle to flow
  7. 13. A component that is represented by an "A" in a circle
  8. 14. A sacrificial component in a circuit that protects against too much current
  9. 15. Like a pressure that pushes electrons through a circuit
Down
  1. 1. Represented by an "x" with a circle around it
  2. 3. Carries the electrical energy
  3. 5. How easy/difficult it is for free electrons to flow through a circuit
  4. 8. A measure of how many electrons are flowing through a circuit
  5. 9. When components are on different loops of a circuit
  6. 12. When opened, the electrons can no longer flow through the circuit
