Electromagnetic

2. the tendency for a material to oppose flow of electrons charging electrical energy into thermal and light energy.
5. un-magnetized iron brought near a magnet becomes magnetized
7. electrons do not flow through circuit.
13. / the amount of electrical energy is conducted to another energy form
14. properties and interaction of magnets
16. materials that does not allow energy to move through easily
17. the rate per unit time . in which electrical energy is transferred by an electric circuit. measured in watts
18. the number of protons and electrons are equal
19. electrons flow through a completed circuit

1. the current only has one voltage to flow through
3. guard against over heating. contains a piece of metal that sends when it gets to hot. bending causes a switch to flip and open the circuit
4. applies to charges in the fact that charges cannot be created or destroyed but only transferred.
6. allow electrons to move easily metals easily flow through
8. a device that increases or decreases voltage of a alternating current
9. the circulation of excess electric charge on an object
10. the flow of electrons
11. two or more batteries form current to move through.
12. Device used to maintain a voltage difference two types Dry-cell and Wet-cell
15. connecting an object to earth with a conductor
16. all things have electric charges
