Electric Field Lines

. Electric field lion is an imaginary line on which of freed small test charge moves in an electric field.
machae  Faraday proposed the idea of Representation of electric field by electric field lines. electric
lines of forces can be  throught a map that represents the direction as well as strength of electric
field. as they give information about of electric force exerted  on a charge. show the lines of commonly
called as lines of force.
. In order to draw the electric field lines, we place positive test charged at equal distances from field charge Q at different places. the electrical field created by positive point charge + Q the positive charge distance the electric lines of forces are directed radially outward.
. The electric field created by negative charge minus the positive test charge. the electric lines of
force in world. positive charge of equal magnitude, the field lines are as shown in figure. the lines in
region between the word charged to each other. the middle region shows the presence of field spot
on natural June.
. For two opposite charges, the field lines starts from positive charge and and or negative and as
shown in figure. for uniform electric field, field lines are parallel equally spaced and lines passing per
unit area is same .
. In this case, the field is uniform in the middle region where field lines are equally spaced as shown
figure.
. Electric field lines start from positive charge and and on the negative charge.
. The Tangent  to the field line at any point give direction electric field at that point.
. Number of electric field lines per unit area passing perpendicularly through an area give the
magnitude of electric field.
. No two electric field lines intersect each other. this is because he has only one direction at any given point. the line cross, I could have more than one direction, which is physically not possible.
. Electric field lines are parallel and equally spaced where the electric field is uniform and non parallel where the electric field is non uniform.

. The lions are closer where the field is stronger and are fartner apart where the field is weaker.
