THERMODYNAMIC EQUILIBRIUM

p2volt =
10-6
.
If
one
imagines
that the
two
plate
systems
can move
relative
to
one
other,
so
that
they
can
be completely
separated,
one
can
get
the
capacitance
to be
of order
of
magnitude 10
after the
plates have been
moved
apart.
If
i
denotes the potential difference resulting
from
p
due
to
the
separation,
one
obtains
r2=
10-6
.
5,000/10
=
0.0005
volt
.
Thus,
if the condenser is short-circuited
when
the plate
systems are
pushed
together, and
the
plates
are
pulled apart
after the connection
has been
broken, potential differences of the order
of
magnitude
of one-half millivolt
will result
between
the plate
systems.
It
does not
seem
to
me
out of
the
question
that these
potential
differ-
ences
may
be
accessible
to measurement. For
if metal
parts
can
be
electrically
connected and
separated
without the
occurrence
of other
irregular potential
differences
of
the
same
order of
magnitude
as
those calculated
above,
then it
must be
possible to
achieve the
goal
by
combining
the
above plate
condenser
[8]
[9]
with
a
multiplier.
We
would
then
have
a phenomenon
akin
to
Brownian motion in
the
domain
of electricity
that could be used
for
the
determination
of
the
quantity
