- 1. Conductors and insulators
- 2. When it comes to the flow of electric current, all materials fall into three categories:
- 3. When it comes to the flow of electric current, all materials fall into three categories: insulators
- 4. When it comes to the flow of electric current, all materials fall into three categories: insulators conductors
- 5. When it comes to the flow of electric current, all materials fall into three categories: insulators conductors resistors
- 6. Insulator – Any material that does not allow electric current to pass through it plastic rubber glass like the protective coating on wires
- 7. Insulator – Any material that does not allow electric current to pass through it plastic cloth wood like the protective coating on wires
- 8. Insulator – Any material that does not allow electric current to pass through it plastic rubber glass cloth wood like the protective coating on wires
- 9. Insulator – Any material that does not allow electric current to pass through it plastic rubber glass cloth wood like the protective coating on wires
- 10. Insulator – Any material that does not allow electric current to pass through it plastic rubber glass cloth wood like the protective coating on wires
- 11. Insulator – Any material that does not allow electric current to pass through it plastic rubber glass cloth wood like the protective coating on wires
- 12. Insulators like plastic and rubber are used as a covering for electric wires. This makes electric wires safer to handle because the insulator protects you from the current.
- 13. Conductor – insulator conductor Any material that allows electric current to pass through it
- 14. Conductor – copper insulator conductor Any material that allows electric current to pass through it
- 15. Conductor – copper aluminum insulator conductor Any material that allows electric current to pass through it
- 16. Conductor – copper aluminum steel insulator conductor Any material that allows electric current to pass through it
- 17. Conductor – copper aluminum steel any metal insulator conductor Any material that allows electric current to pass through it
- 18. Conductive material (metal) is used for wires that will carry electricity. insulator conductor
- 19. A material or a device that allows some current to pass but converts some of the current to another form of energy. Resistor Light energy Motion energy Heat energy Sound energy
- 20. into light energy Motion energy eat energy Sound energy These appliances have resistors that convert electrical energy into light energy.
- 21. Light energy Motion energy Heat energy Sound energy These appliances have resistors that turn electrical energy into motion energy.
- 22. Light energy Motion energy Heat energy Sound energy These appliances have resistors that change electrical energy into heat energy.
- 23. These appliances have resistors that convert electrical energy into sound energy.
- 24. Useful electric current can only move through a path of conductive material.
- 25. Useful electric current can only move through a path of conductive material. This path is called a …..
- 26. Circuit A path for electric current
- 27. An electric circuit might be open or closed. A path for electric current
- 28. Closed Circuit An unbroken path for electric current (no gaps, current can flow). The light is on
- 29. Open Circuit A path for electric current that has a gap (no current can flow). gap The light is off
- 30. Most electrical devices have a switch in the circuit to make it easy to close (turn on) and open (turn off) the circuit.
- 31. Switch A tool to open and close a circuit switch
- 32. A circuit can also be opened and closed by touching two wires together. Open circuit Closed circuit No current can flow current can flow
- 33. A circuit can also be closed by touching those two wires to a conductor. ed circuit current can flow
- 34.
