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
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.
