U+2130 Script Capital E

U+2130 wurde in Version 1.1 in 1993 zu Unicode hinzugefügt. Er gehört zum Block U+2100 bis U+214F Letterlike Symbols in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Uppercase Letter und wird allgemein verwendet, das heißt, in keiner speziellen Schrift. Das Schriftzeichen ist auch bekannt als emf (electromotive force).

Das Zeichen ist eine Schriftart Variante des Zeichens Zeichen für U+0045 Latin Capital Letter E. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text wird es von links nach rechts geschrieben. Bei einem Richtungswechsel wird es nicht gespiegelt. Das Wort, das U+2130 mit ähnlichen Zeichen bildet, verbietet in sich Zeilenumbrüche. Der Buchstabe kann mit einem anderen Zeichen verwechselt werden.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, denoted E ) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf by converting other forms of energy into electrical energy. Other types of electrical equipment also produce an emf, such as batteries, which convert chemical energy, and generators, which convert mechanical energy. This energy conversion is achieved by physical forces applying physical work on electric charges. However, electromotive force itself is not a physical force, and ISO/IEC standards have deprecated the term in favor of source voltage or source tension instead (denoted U s ).

An electronic–hydraulic analogy may view emf as the mechanical work done to water by a pump, which results in a pressure difference (analogous to voltage).

In electromagnetic induction, emf can be defined around a closed loop of a conductor as the electromagnetic work that would be done on an elementary electric charge (such as an electron) if it travels once around the loop.

For two-terminal devices modeled as a Thévenin equivalent circuit, an equivalent emf can be measured as the open-circuit voltage between the two terminals. This emf can drive an electric current if an external circuit is attached to the terminals, in which case the device becomes the voltage source of that circuit.

Although an emf gives rise to a voltage and can be measured as a voltage and may sometimes informally be called a "voltage", they are not the same phenomenon (see § Distinction with potential difference).
