Question

what do you mean by electrical field line

​

Answer 1

Answer:

Electric field lines in an electric field are imaginary lines, the tangent to which, at any point, gives the direction of the electric field intensity. In simpler version, it can be said, an electric field line is a path along which a positive charge would move, if it is free to do so.

Answer 2

What is Electric Field Line?

Electric field lines are an excellent way of visualizing electric fields. They were first introduced by Michael Faraday himself.

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.

Properties of Electric Field Lines:-

• The field lines never intersect each other.

• The field lines are perpendicular to the surface of the charge.

• The magnitude of charge and the number of field lines, both are proportional to each other.

• The start point of the field lines is at the positive charge and end at the negative charge.

• For the field lines to either start or end at infinity, a single charge must be used.
