The electric force between two particles with charges of q1 and q2
(When E=0, then Fon q=0)
- denser lines = stronger field
- If the source charge is positive, the electric field vectors point away from it
- If the source chare is negative, then the field vectors point toward it
- Electric field vectors can be added like any other vectors
- metals best ex of conductors, or aq. solutions contain dissolved electrolytes
- Any excess charge on a conductor resides entirely on outer surface
- No electro static field within the body of a conductor
- Electric field is always T to surface
- ratio of change in potential energy to the charge would be the same --> says something about the FIELD and the DISPLACEMENT but not the charge that made the move
- electric potential is electrical potential energy per unit charge (J/C = V)
Words From Our Students
"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"
Alice, Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"
Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
