Question

What are electric field lines? Mention its two properties

Answer 1

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.
