Electric Field Flashcards
What is a field?
A region in which an object will experience a force at a distance
How is an electric field created?
Charge objects
Charge objects in an electric field experience…
Force
What so electric field strength?
The force experienced per unit positive charge at that point.
What direction do electric fields go?
From positive charge to negative charge
The closer the lines…
The grater the electric field strength
What is Coulomb’s law?
Any two point charges exert an electrostatic force on each other that is directly proportional to the product on their charges and inversely proportional to the square of their separation.
As you move further away from the electric field what happens to the strength of the field…
Decreases
What are the factors affecting the capacitance of a capacitor?
Separation between the plates
Area of the overlap
Insulation used between the plates.
Electric potential
The work done per unit charge in bringing a positive charge from infinity to that point in space.
Electric potential difference
The work done per unit charge between two points around the particle of charge Q.
