Electric fields Flashcards
1
Q
What is an electric field strength
A
The force experienced per unit positive charge at that point.
2
Q
Characteristics of electric fields
A
Always in the direction of positive to negative
3
Q
Electric field patterns
A
Arrows show direction of field.
Field lines are always perpendicular to surface of conductor
Closer field lines depict greater field strength
4
Q
Coulombs law
A
Two point charges exert an electrostatic force on each other that is directly proportional to the product of their charges and inversely proportional to the distance between them squared.
