Across
  1. 1. the rate at which energy is transformed from one form to another
  2. 4. electricity a buildup of electrical charges on an object
  3. 6. distance the wave travels in one cycle (crest to crest) or (trough to trough)
  4. 8. highest point on the wave
  5. 11. amount of waves that pass a given point in one second, measured in hertz (waves per second) abbreviated hz
  6. 12. a material that does not allow free movement of electrical charges (electrons)
  7. 13. Circuit a complete, unbroken path through which electric charges (electrons) flow
  8. 14. transfer energy from one place to another
  9. 16. lowest point on the wave
  10. 18. a combination of two or more electrochemical cells in a row
Down
  1. 2. motion of charged particles and the energy derived from that motion
  2. 3. Circuit an electric circuit with multiple paths
  3. 5. a material through which electrical charges (electrons) can easily flow
  4. 7. tells how much energy the wave has
  5. 9. Circuit an electric circuit with a single path
  6. 10. the measurement of how difficult it is for electrical charges to flow through a circuit
  7. 13. Current the rate at which electrical charge flows through the wire in a circuit
  8. 15. the difference if electrical potential energy between two places in a circuit; the cause of electron movement
  9. 17. a device which draws current from a circuit, providing resistance to the flow of electricity
