Electrical length is defined for conductors carrying alternating current (AC) at a single frequency or narrow band of frequencies. An alternating electric current of a single frequency is an oscillating sine wave which repeats with a period of = /. [5]
The ampere is an SI base unit and electric current is a base quantity in the International System of Quantities (ISQ). [4]: 15 Electric current is also known as amperage and is measured using a device called an ammeter. [2]: 788 Electric currents create magnetic fields, which are used in motors, generators, inductors, and transformers.
The current British Standard for metallic materials including wire is BS 6722:1986, which is a solely metric standard, superseding 3737:1964, which used the SWG system. The IEC 60228 , used in most parts of the world, defines standard wire sizes based on their cross-sectional areas as expressed in mm 2 . [ 3 ]
The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...
In the North American electrical industry, conductors thicker than 4/0 AWG are generally identified by the area in thousands of circular mils (kcmil), where 1 kcmil = 0.5067 mm 2. The next wire size thicker than 4/0 has a cross section of 250 kcmil. A circular mil is the area of a wire one mil in diameter. One million circular mils is the area ...
The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
Electrical measurements are a branch of the science of metrology. Measurable independent and semi-independent electrical quantities comprise: Voltage; Electric current; Electrical resistance and electrical conductance; Electrical reactance and susceptance; Magnetic flux; Electrical charge by the means of electrometer; Partial discharge measurement
