![]() A small charge is generated on the surface of the material to be painted and opposite charge is generated in the paint to be applied. The paint that touches the surface of the material sticks as the opposite fields attract. This helps painters to easily find the surface where charge is attracted and repelled and paint accordingly. Uses of electric field lines in daily life:Įlectric field lines also play a major role in the day to day life. Some painters for example use electric field in their paintings. Here image “a” represents a correctly drawn electric field pattern where as image “b” represents an incorrectly drawn electric field. The electric field lines terminate perpendicularly to the surface of a conductor. The strength of the electric field at the region is based on the density of the electric field lines. The electric field lines never intersect each other. The net electric inside the conductor should be zero.Įlectric field lines from a positive charge is drawn radially outwards and electric field line from a negative charge is drawn radially inwards. There are certain rules and procedures to be followed while drawing an electric field. The following rules must be followed.Įlectric field lines should be drawn from high potential to low potential. Then the flux over the surface integral of the vector field can be given as, Φ E = Q ε 0 \right) Φ ( V ) = V i ⊂ V ∑ Φ ( V i ) Electric field lines start from a positive charge and end at a negative charge, in case of a single charge, electric field lines end at infinity In a charge. It proposes that the electric flux flowing through any surface that is closed is directly proportional to the total electric change acting on that same surface. Electric field or electric displacement field can be used in defining Gauss law. It is also known as Gauss's flux theorem. Gauss’ law relates the distribution of electric charge to the resulting electric field. Gauss Law for electric field that the distribution of electric charges readily leads to the generating of static electric field. Thus, the electric field intensity at the point will have two directions, which is absurd.Gauss law helps in explaining the relation of the electric charge. If the electric field lines intersect, then two tangents could be drawn at their point of intersection. Why don't electric field lines intersect \(?\) Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would. Also, this is the path on which a positive test charge will tend to move if free to do so. These imaginary lines are called electric lines of force.
