What do you mean by electric field lines Class 12?

What are electric lines?

An electric line of force is an imaginary curve drawn in such a way that tangent to this curve at any point gives the direction of the electric field at that point. It can be a path with maybe a curve or a straight line.

What are the properties of electric lines of force?

Following are the 3 properties of electric lines of force.

  • The electric lines of force start from a positive charge and ends on a negative charge.
  • The electric lines of force always enter or leave the charged surface normally.
  • Electric lines of force can never intersect each other. Was this answer helpful?

What are the properties of field?

Mathematicians call any set of numbers that satisfies the following properties a field : closure, commutativity, associativity, distributivity, identity elements, and inverses.

What does electric lines of force represent?

Electric lines of force represents the direction of electric field. Electric lines of force can be defined as a way or path, it may be straight or curved, so that the tangent at any point to it gives the direction of the electric field intensity at that point.

Who explained electric lines of force?

The concept of lines of force was introduced into physics in the 1830s by the English scientist Michael Faraday, who considered magnetic and electric effects in the region around a magnet or electric charge as a property of the region rather than an effect taking place at a distance from a cause.
