Electric Field region in space around a charge or charged body, where the charge has its electrical effect, is called the electric field of the charge. Electric field intensity at a point in an electric field is the force experienced by a unit positive charge placed at that point. Electric lines of force is an imaginary curve, the tangent to which at a point gives the direction of intensity at that point. Let's know more about Electric Field.
