intro to electric fields
- 2. ELECTRIC FIELD When two object are rubbed together, electrons are transferred from one surface to another causing the objects to become charged
- 3. The object that gain electrons become negatively charges
- 4. The object that looses electrons becomes positively charged
- 5. Quick Experiment Take a balloon and blow air into it. Tie the balloon on top and rub it against your hair Place an empty can on the ground and continue rubbing the balloon Move the balloon closer to the empty can and observe
- 6. Quick Experiment • NOTE THAT WHEN YOU MOVE THE BALLOON CLOSE TO THE CAN, it MOVEs closer to THE BALLOON
- 7. ELECTRIC FIELDS • ELECTRIC FIELDS ARE REPRESENTED BY ELECTRIC FIELD LINES • THE FOLLOWING SHOULD BE NOTED WHEN DRAWING ELECTRIC FIELD LINES:
- 8. ELECTRIC FIELDS 1. Electric fields line are always directed away from the positive charge to the negative charge 2. The lines never cross or touch each other 3. Field lines are drawn perpendicular to a charge or charged surface 4. Field lines are drawn closer together where the field is stronger
- 9. NOTE!!! •Like charges will repel each other
