There are two categories(types) of electricity: 3. There are two categories(types)of electricity: Current electricityCurrent electricity can be used by people. when electrons flow through a circuit. 4. There are two categories(types)of electricity: Static electricitywhen electrons build up on an insulator (rubber, clothing, non-metals) causing an imbalance. The charge of static electricity is sometimes discharged (balanced) by a spark. This type of electricity is not used much by people, but can be fun (and sometimes dangerous). 5. </p> <ul><li>Static</li></ul> <ul><li>electricity </li></ul> <p>6. </p> <ul><li>Static electricity </li></ul> <p>7. </p> <ul><li>Everything is made of tiny particles calledatoms. </li></ul> <p>8. </p> <ul><li>Atoms have positively (+) chargedprotonsin the middle</li></ul> <p>+ + 9. </p> <ul><li>Atoms have positively (+) chargedprotonsin the middle</li></ul> <ul><li>and negatively chargedelectrons(-) orbiting quickly around them.</li></ul> <p>_ + _ + 10. </p> <ul><li>Protons always stay with their atom,but electrons sometimes move to different atoms.</li></ul> <ul><li>Traveling electrons are what we know as electricity. </li></ul> <p>11. When more negatively charged electrons are on an object it has a negative charge. If electrons have been taken away, the object will be have a positive charge because it is out of balance toward the positive protons. 12. Your body is an object that can become unbalanced with a negatively charge when you shuffle your shoes on a carpet. The spark that jumps from your hand to the doorknob balances your static charge.You have to walk on the carpet some more to get another spark. 13. </p> <ul><li>Two objects with static charges can attract or repel each other much like magnets.</li></ul> <ul><li>If the charges are the same(both positive or both negative)the objects will repel just like magnets.</li></ul> <ul><li>If the charges are different, they attract.</li></ul> <ul><li>(Opposites attract) </li></ul> <p>+ + _ _ 14. Different charges attract Charges that are the same repel each other. 15. The reason this hair looks so funny is because each hair has the same static charge.Each hair is repelling all the others. 16. 17. 18. 19. </p>
