The Central Point Of The Circuit
Category: FIRST PRINCIPLES.
Source: A Newly Discovered System Of Electrical Medication
The central point of the circuit--that point which divides between its
positive and negative halves--is reckoned, in practice, to be the
midway point in the line over which the current passes, in its whole
course from the positive post around to the negative post. When the
cords are of equal length, this point will always be in the person of
the patient, about midway between the parts where the two electrodes are
applied. This central point, or "point of centrality," is practically
neuter--neither positive nor negative; and upon the two opposite halves
of the circuit, the positive and negative qualities of the current are
in greatest force nearest to the posts, and in least force nearest to
the central point. At this point they cease altogether, and the central
point is neuter.
It may, perhaps, be observed that, in apparent contradiction of this
statement, the sensational effect of the current on the negative half
of the circuit is least nearest to the positive post, and becomes
regularly greater as the current advances towards the central point;
and that at this point it is greater than at any other point between
this and the positive post. To relieve this seeming contradiction, it is
only necessary to consider that, in fact, the positive state on the
negative half of the current does increase regularly from the
positive post to the central point. But that which is the increase of
the positive state is the decrease of the negative state. So it is
still true that on the negative half of the circuit, the negative
qualities diminish as we advance towards the central point just as on
the positive half, the positive qualities diminish regularly towards
the central point, as stated above.
