electrical line of force

• Ligne imaginaire ou trajectoire dans un champ électrique le long de laquelle se déplacerait une charge d'essai positive, utilisée pour visualiser la direction et l'intensité du champ électrique.

An imaginary line or path in an electric field along which a positive test charge would move, used to visualize the direction and strength of the electric field.

   An imaginary line used to represent the direction and strength of an electric field, where the tangent at any point gives the direction of the electric field vector.

   • The electrical lines of force emanate from positive charges and terminate on negative charges.
   • In a uniform electric field, the lines of force are parallel and equally spaced.
   • The density of electrical lines of force indicates the strength of the electric field.
