Electric Fields Flashcards
1
Q
Electric field, E
A
Electric force per unit charge acting on a small positive test charge placed at that point.
2
Q
Electric potential, V
A
The work done per unit charge by an external force in moving a small positive test charge from infinity to that point without any change in KE.
3
Q
Electric potential energy, U
A
Work done by external force in moving the charge from infinity to that point without any change in KE.
4
Q
Coulomb’s law
A
The magnitude of the electric force between 2 points is proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between them.
