define electric field lines
Answers
Answer:
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.
Explanation:
Electric Field Lines
Field line is a locus that is defined by a vector field and a starting location within the field. For the electric fields, we have electric field lines. As we have seen in Electrostatics, electric charges create an electric field in the space sorrounding them. It acts as a kind of "map" that gives that gives the direction and indicates the strength of the electric field at various regions in space. The concept of electric field lines was introduced by Michael Faraday, which helped him to easily visualize the electric field using intuition rather than mathematical analysis.
Answer:
Electric field lines are an excellent way of visualizing electric fields. They were first introduced by Michael Faraday himself.
A field line is drawn tangential to the net at a point. Thus at any point, the tangent to the electric field line matches the direction of the electric field at that point. Secondly, the relative density of field lines around a point corresponds to the relative strength (magnitude) of the electric field at that point. In other words, if you see more electric field lines in the vicinity of point A as compared to point B, then the electric field is stronger at point A.
