6.2 - Electric Fields Flashcards
1
Q
What is an electric field?
A
Region around a body where other charged bodies feel a force due to electric charge of the body
2
Q
What do electric field lines show?
A
Shape of the field
Direction of a positive charge
3
Q
What is electric field strength?
A
Force per unit of positive charge
4
Q
What is coulombs law?
A
Force between two point charges is directly proportional to the product of charges. It is also inversely proportional to the square of their separation
5
Q
What is permittivity?
A
A constant which is related to the size of the capacitance. C = Aɛ / d
6
Q
What is Electric potential?
A
Work done per unit of positive charge to move the charge from infinity to a point within the electric field
