By definition E field lines cannot intersect (for that matter, the lines
don't actually exist, but are a means of visualizing the field.  They are,
by definition, parallel to the gradient of the efield at any given point.


If you are drawing a 2-D picture of the field, and you draw lines for
equipotentials (much like contour lines on a topographical map), then the
"field lines" are perpendicular to the equipotential lines. Since a field
line doesn't really correspond to anything other than the direction of the
field gradient (i.e. the volts per meter maximum), the density of them is
arbitrary (usually chosen for explanatory purposes). And, because of the
way they are defined, they cannot intersect (although they can meet at a
point charge, which can't exist in nature)

What IS important is how far apart the equipotential lines are, that is,
what the magnitude of the gradient is, because that is where the force on
the ions is greatest, and where breakdown is most likely to occur.  To go
to the topographic map example, it's where the terrain is steepest.
