Module 1: Lessons 4 + 5 Flashcards
1
Q
What indicates strength and weakness of electrical field on a electrical field map.
A
A field is strong if there are many field lines, and weak if there are few field lines.
2
Q
Do field lines cross?
A
NO, then it would be ambiguous.
3
Q
What is electric potential energy and its corresponding symbol.
A
Energy stored in the electric field; Ue
4
Q
What is the equation for Ue?
A
Ue = k q1 q2 / r
5
Q
What is the equation for a point charge?
A
Ue / q(test) = k Q / r
6
Q
What is the equation for potential energy change
A
delta Ue = delta V q
