All the laws of the universe are directly a reflection of the action
that Newtons laws
pertain to. All Newtons laws pertain to relative movement of mass
which is comprised of time, mass and relative distance to form a state
of equilibrium.
We all know how mechanical laws are conneted to Newton but how is
electricity essentially the same? We all know that magnetism is a
reflection of the smallest dipole
relative angle at any point in time. We also know that this dipole can
also turn during a period of time such that the magnetic field of
force at any point in time is reflected by the angle that the dipole
takes. This dipole in electrical terms is a microsom of the large
mechanical forces in relative movement.
For electricity the dipole takes up an alignment that reflect the
current flow at any point and place in time. Thus with a dc current
all the dipoles aligne with each other with respect to the current
flow in a two dimensional form. When applying an alternating current
we are also really applying a DC current but with a rotational or
three degrees of freedom such that at any point in time all dipole
alignment reflect the torque angle at that particular point which is
NOT the same as any other dipole point alignment.
Thus when current is not applied the molecular dipole arrangement fall
back to the directions it had prior to the onset of current to provide
a stated of equilibrium.
In the case of a DC current supplied the microscopic dipoles ALL have
the same alignement and when the current ceases to be applied the
dipoles still stay in alignment with each other. So in effect ,the
movement of the micro dipole in electricity is exactly the same as a
mechanical element where all the forces of the electrical dipoles are
summated. There are difference with mechanical elements which can be
determined by its mass and structural make up such as how they perform
in a magnetic field. Earlier we expressed the strength of a magnetic
field is measured in part by the angular position of its resident
dipoles.For a true magnet formed with a ferrous material the
atmosphere can permeate all of the material as it changing its
composition, but in the initial state the total mass is a reflection
of the number of inherrent dipoles which in summation is a measure of
the potential energy contained. With a current carrying
element such as aluminum when it is exposed to the atmoshere it
immediately forms a barrier to prevent the ongoing penetration of
oxidtion. Thus when a current is applied
it can only affect the dipoles in the protective skin depth of the
pattina and not affect the internal unoxidizes material where it can
oxidize and decay as with a ferrous material.
Thus the pattina can only hold a smaller number of dipoles which
reflects a smaller potential energy for generating a magnetic field.
Thus both electrical and mechanical
formats surround the facts of potential energy and kinetic energy when
in a state of equilibrium as espoused by Newtons laws.
Have a happy day
