Electric field lines do not pass through a conductor, this shows that electric field inside a conductor is always zero. The number of field lines originating or terminating at a charge is proportional to the magnitude of that charge. Thus, the electric field direction about a positive source charge is always directed away from.

District department of transportation curbside management study. Draw the electric field lines between two points of the same charge. The electric field strength is exactly proportional to the number of field lines per unit area, since the magnitude of the electric field for a point charge is latexek\fracqr2\\latex and area is proportional to r 2. He also shows how to determine the direction of the electric force on a charge. Electricity and magnetism african virtual university.

A field line is a graphical visual aid for visualizing vector fields. Field lines never cross each other if they do so then at the point of intersection there will be two direction of electric field. Electric field lines either originate on positive charges or come in from infinity, and either terminate on negative charges or extend out to infinity.
