e-field Flashcards
1
Q
electric field
A
a region of space where a stationary charge experiences electric force
2
Q
electric field strength
A
force per unit positive charge experienced by a small stationary test charge at that point in the electric field
3
Q
electric potential
A
work done per unit positive charge by an external force in bringing a small stationary test charge from infinity to that point in the electric field
4
Q
electric field strength @ a point
A
numerically equal to the potential gradient at that point
5
Q
coulomb’s law
A
electric force between two point charges is directly proportional to product of two charges and inversely proportional to the square of separation between the two charges
