 Electrical element - Wikipedia, the free encyclopedia
An electric circuit, or electrical network, consists of electrical elements or components connected by conductors.
However, there is a distinction between real electrical components and the ideal electrical elements by which they are represented.
Current sources are often absent from basic electric circuits, and are more likely to be found in electronic circuits containing semiconductors.

 US Patent 4,595,975 Edwin Gray "Efficient Power Supply Suitable for Inductive Loads"
The increase in efficiency anticipated in converting the electrical energy to mechanical energy within the inductive load is attributed to the utilization of the most optimum timing in introducing the electrical energy to the load device, for the optimum period of time.
In operation the high-voltage, short-duration electric spike is generated by discharging the capacitor 16 across the spark-gap in the conversion switching element tube.
When the energy source is a direct-current electric energy storage device, such as the battery 12, the input to the bridge rectifier is provided by the voltage step-up transformer 22, that is in turn energized from the vibrator 20, or solid-state chopper, or similar device to properly drive the transformer and rectifier circuits.

 Wheel of Motion
To determine the configuration of the motion for a particular element, append its value of electrical displacement to the two values of magnetic motion shown for the element at the top of the circle in which the element appears.
Proceeding clockwise at the 0 degree point and adding motion, in increments of electrical displacement, to an element's existing value of motion, produces the successive elements of atomic numbers until the 180 degree position of the circle is reached.
Therefore, the number of total electrical displacements in a circle, and thus the total number of element positions available in a circle, is twice the electrical equivalent of the magnetic motion that produces the unit of speed displacement at that point in the progression.

 Electrical Circuit Breakers
Electrical energy is transported throughout an electrical circuit by the conductive path provided by electrically insulated wires.
Electrical engineers tell us that the two major factors that govern the amount of fault current that can be delivered in a system are the KVA rating of the transformer and the impedance of the transformer.
While many electrical circuits are wired using copper conductors, copper-only contacts are not used because heating causes a type of corrosion that increases the contact’s impedance, which in turn increases the amount of heat generated.

The electrical conductivity of a tested solution is affected by the concentration of its elements.

 Switch Definition
Actuation and Deactivation Point - The actuation point (sometimes called set point) is the exact point at which the electrical circuit controlled by the switching element is opened (or closed) on increasing pressure.
The deactivation point is the opposite, or the point at which the electrical circuit is closed (or opened) on decreasing pressure.
If the pressure then drops and the switch deactivates (returns to its normal condition) at 90 psi, it is said to have a deadband of 10 psi.

In a dielectric material an electric field can be established without allowing a significant flow of charge through it.
If two pieces of conducting material are separated by a dielectric material, an electric field is established between the conductors when charge flows into one conductor and out of the other.
This electric field results in a potential difference between the two conductors which depends on the amount of charge placed on the conductors.
