E Field Flashcards
1
Q
Electric Field
A
An electric field is a region in space where a stationary charge experiences an electric force.
2
Q
Electric Field Strength
A
The electric field strength E at a point is the electric force per unit positive charge acting on a small stationary charge placed at that point.
3
Q
Electric Potential
A
The electric potential at a point in an electric field is defined as the work done per unit positive charge by an external agent in bringing a small test charge from infinity to that point without a change in the kinetic energy of the charge.
4
Q
Coulomb’s law
A
The magnitude of the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between
