Electric field line
Electric field lines are a visual representation of the electric field around an electric charge.
In the case of a point charge, it can be expressed in spreading around the charge.
The denser the electric field line, the stronger the electric field.
- The electric field line starts at the (+) charge and ends at the (-) charge. Or, it may start or end at infinity.
- When drawing lines, the number of lines is proportional to the amount of electric charge.
- Electric field lines do not intersect or separate from each other.
- The electric field line starts or ends perpendicular to the conductor surface.
- Electric field lines do not exist in a conductor (electric field = 0).
- A uniform electric field has the same distance between the lines of force.
Between the same kind of electric charge, a line is connected, and a pulling force acts.
The lines do not connect between the different kinds of electric charges and the pushing force acts.
