Electric field at a point in
the space around a system of charges tells you the force a unit positive
test charge would experience if placed at that point (without disturbing
the system) Electric field is a characteristic of the system of charges and
is independent of the test charge that you place at a point to determine
the field The term field in physics generally refers to a quantity that is
defined at every point in space and may vary from point to point Electric
field is a vector field, since force is a vector quantity
