Electric field
|
A region in which an attractive or repulsive force is experience by an object with charge
|
|
|
Electric field strength
|
Force per unit charge
it is a vector |
|
|
Coulomb's law
|
The force between two charges in a vacuum is proportional to the product of the two charges and inversely proportional to the square of the distance between them
|
|
|
Electric potential
|
Potential energy per unit charge
|
|
|
Potential difference
|
Energy needed to move a unit charge from one potential to another
|
|
|
If the charges were not in a vacuum...
|
the size of the force between them would also depend of the permittivity of the material between them
|
