The Electric Circuit
Category: FIRST PRINCIPLES.
Source: A Newly Discovered System Of Electrical Medication
The Electric Circuit is made up of any thing and every thing which
serves to conduct the electric current in its passage--outward and
returning--from where it leaves the inner surfaces of the zinc plates in
the battery cell to where it comes back again to the outer surfaces of
the same plates. When the conducting-cords are not attached to the
machine, or when the communication between the cords is not complete, if
the machine be running, the circuit is then composed of the battery
fluid, the platina plate, the posts, the connecting-wires, which unite
the battery with the helix, the helical wires, and their appendages for
the vibrating action. But when a patient is under treatment, the
conducting-cords, the electrodes, and so much of the patient's person as
is traversed by the current while passing from the positive electrode
through to the negative electrode, are also included in the whole
circuit. And whatever elements may serve to conduct the current in any
part of its circuit--be they metal, fluid, nerve, muscle, or bone--the
same are all, for the time, component parts of one complete magnet,
which, in all its parts, is subject to the law of polarization,
precisely as if it were one magnetized bar of steel. Usually, however,
it is sufficient for practical purposes to contemplate the circuit as
consisting only of that which the current passes through in going from
the point where it leaves the positive post and enters into the negative
cord, around to the point where it leaves the positive cord and enters
into the negative post.
