Electric Field Lines

Introduction on electric field lines:

Scientist Michael Faraday introduced the term electric field in 19 th century. Faraday was born in Newington Butts. Faraday’s perceptions that the pattern of electric field lines characterizing the electric field are invisible in reality. He explained that around a charge particle there a space in which another charge particle experience a force of attraction or repulsion, this region is called the electric field. He gave that electric field lines are vector in nature. I like to share this Electromagnetic Spectrum Wavelength Chart with you all through my article.



Definition of electric field lines:

Electric field lines are the curved or straight paths along which a unit positive charge tends to move in the electric field if it is free to do so. The direction of electric field lines gives the direction of motion of unit positive charge if it is free to do so. The electric field lines are imaginary but they give us the pictorial visualization of electric field. It is useful to draw a pattern of several lines, which extend between infinity and the source charge. These patterns of lines are electric field lines. Electric field lines are also called as electric flux lines. Please express your views of this topic Momentum Problems by commenting on blog.


Properties of electric field lines:

(i) If the electric field is due to isolated charge then the electric field line is always straight.

(ii) If the electric field is due to two or more charges then the electric field line are always straight.

(iii) The electric filed lines are directed away from positive charge and directed towards the negative charge.

(iv) A unit positive test charge tends to move along the electric field line if it is free to do so.

(v) Electric field lines are imaginary lines.

(vi) The tangent at any point to the electric field line gives the direction of electric field at that point.

(vii) Two electric field lines never cross each other.

(viii) If the electric field is stronger in any region then electric field lines are crowded, and the electric filed lines are spread out if the electric field is weaker in any region.

(ix)Electric field lines contracts lengthwise.

(x) Electric field lines cannot pass through the conductor.

(xi)Electric field lines can pass through the non-conductors and dielectrics.
