The path of electric current through a conductor.
The flow of electrons in a circuit.
2. Electric field lines originate from charges and terminate on charges.
negative, positive
positive, positive
positive, negative
negative, negative
1. Electric field lines can cross each other.
True
False
2. The strength of an electric field is inversely proportional to the square of the distance from the charge.
True
False
1. An electric field is a vector quantity, meaning it has both and .
2. The unit of electric field strength is per .
1. Describe how a positive test charge would behave when placed in the electric field of a negative point charge.
2. What is the difference between an electric field and an electric force?
Observe the electric field lines for a positive point charge. The lines point away from the positive charge.
Using the diagram above as a reference, sketch the electric field lines for a negative point charge.
