Electric field lines cannot create a tight loop since the electromagnetic field is conservative.Īn electric field is a space effect that causes a charge to experience a force.Two electric field lines will never cross or intersect. ![]() Electric field lines are constant and seamless in the free region.In the case of a sole charged electric field, lines finish at infinity.Charge lines begin with a positive charge and end with a negative charge.Electric field lines have arrows that show the direction of the electric field because it is a vector. With the use of electric field lines, the electric field can be determined. ![]() Wherein E is the electric field intensity. The force produced by a charge is determined as F = qE in an electric field. The vector sum of the intensities generated by the individual charges equals the intensity of the electric field at any position because of several charges. The intensity of the electric field at a point d unit distant from a point charge q is given by the expression:Įlectric Field Intensity (E) = F/q, here F is Coulomb force and q is the charge.
