Dipole System
Assume that
q
and
q
being two charges with the same amount of energy but opposite directed. If the distance (very little separation) between the two charges is
d
, the voltage
V
between
q
and
q
will be expressed as:
where
P
=
q
d
and
R
is the vector from the middle of
d
to the point where the voltage is measured.
