Electric field line
Electric field lines are a visual representation of the electric field around an electric charge.
In the case of point charge, it can be expressed in the form of spreading around the charge.
At a certain position, the direction of the electric field becomes the tangential direction of the electric field line, and 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 of electric force connects and a pulling force acts.
Between different kinds of electric charges, the electric line of force does not connect and the pushing force acts.
