Measurement of electrical quantities may be done to measure electrical parameters of a system. Using transducers , physical properties such as temperature, pressure, flow, force, and many others can be converted into electrical signals, which can then be conveniently measured and recorded.

Leszek S. Czarnecki (born May 14, 1939) is a Polish-American electrical engineer and professor emeritus at Louisiana State University (LSU). He is known for his work on power theory in electrical circuits, particularly the development of the Currents' Physical Components (CPC) Power Theory.
The Hawkins Electrical Guide was a technical engineering book written by Nehemiah Hawkins, first published in 1914, intended to explain the highly complex principles of the new technology of electricity in a way that could be understood by the common man.

In electrical engineering, characteristics like current or voltage can be measured by an ammeter, a voltmeter, a multimeter, etc.The ammeter is used in series with the load, so the same current flows through the load and the ammeter.
Many of the parts of this series have been harmonized by CENELEC CLC/SR 66 "Safety of measuring, control, and laboratory equipment" [1] as EN standards, and almost all of them eventually get published in the Official Journal and receive Presumption of Conformity for the EU Low Voltage Directive, as seen in the lists of harmonised standards (PDF Version).
