As electric field, that is, force per unit charge is a vector quantity; it can be used to represent overall effect of electric field in system of electric charges. Similarly electric field can be used in pictorial form to describe the overall intensity of the field.

1. Electric Field Lines

2. Definition
 Electric field lines describe the nature of electric
field in pictorial form
 We can easily reveal direction, strength and other
properties of electric field

3. Nature of electric field lines
 Electric field lines move away from positive
charge and move towards negative charge
 Electric field lines are conservative in nature
 Electric field lines start from positive charge and
terminate at negative charge
 If there is only one charge, then electric field
terminate at infinity

4. Properties of Electric Charge
 Direction of electric field can be revealed by
drawing tangents at a point
 Electric field lines can’t pass through a conductor
 Number of electric field lines is directly
proportional to strength of electric field

5. Some more properties
 Electric field lines are closer where there is strong
electric fields and far in case of weak electric
fields
 Electric field never intersect each other, if this
were so then a point will have two directions of
electric field, which is not possible
