Electricity is an act of
affinity by the electron flow, through extra electrons in the valence
shell of the atom, sharing through a medium of copper wiring of the
electrons down a line in one direction. The wiring is rated by load,
and is the measurement of voltage on a line of copper wiring. What the
electricty does, is flow through and runs applications, by flowing
through designed circuit boards with timers, volt drops, and loop
circuitry. Then, electricity flows from the appliance, back to the
source of the electricity. When the electrical flow goes back to the
source of the flow. The voltage is not the same due to heat generation.
This is called the voltage drop measurement.
To
measure it, use a volt meter across the copper line from the start of
the electrical line to where it enters the application, and record the
reading at that point, calling it voltage 1. Then, the next stage, is
to record the reading from where the electrical line comes from the
application, to where the line is going back to the source, which is
the line end. Call this voltage 2. Now, substract the voltage 2 reading
from the voltage 1 reading and the result is the Line Load. If the line
load is greater than the line load wire rating, it will result in
overloaded circuits or wires.
Where
there are too many applications, like a hair dryer, a couple of lights,
two spotlights, and one portable stove on the same circuit, there will
be overloaded burned wires, with possible fire hazard, that are burned
useless for carrying electricity current. The way electricity flows, is
decided by the phycisits and engineers philosophy. Engineers say,
electricity flows from negative to positive Phycisitssay, electricity
flows positive to negative. Affinity properties of like goes to like,
through the atomic valence shell makes electricity work.
