CoulombThe coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). It is defined to be equal to the electric charge delivered by a 1 ampere current in 1 second, with the elementary chargee as a defining constant in the SI.
Electric currentAn electric current is a flow of charged particles, such as electrons or ions, through an electrical conductor or space. It is defined as the net rate at which electric charge flows through a surface. The moving particles are called charge carriers, which may be of several types, depending on the conductor. In electric circuits, the charge carriers are often electrons moving through a wire. In semiconductors, the charge carriers can be electrons or holes.
International System of UnitsThe International System of Units, internationally known by the abbreviation SI (from its official French name, Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement. It is the only system of measurement with official status in nearly every country in the world, employed in science, technology, industry, and everyday commerce.
Elementary chargeThe elementary charge, usually denoted by e, is the magnitude of the charge on an electron and a fundamental physical constant defined to be exactly e = 1.602176634×10 C. The elementary charge is a measure of the coupling strength of the electromagnetic force and one of the seven defining constants of the International System of Units (SI).
MetreThe metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1/299792458 of a second, where the second is defined by a hyperfine transition frequency of caesium.
2019 revision of the SIIn 2019, four of the seven SI base units specified in the International System of Quantities were redefined in terms of natural physical constants, rather than human artefacts such as the standard kilogram.
ElectromagnetismIn physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism describes and relates the three distinct but closely intertwined phenomena of electricity, magnetism, and optics.
André-Marie AmpèreAndré-Marie Ampère (20 January 1775 – 10 June 1836) was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as electrodynamics. He made also important contributions in chemistry and philosophy. He is also the inventor of numerous applications, such as the solenoid (a term coined by him) and the electrical telegraph.
Hans Christian ØrstedHans Christian Ørsted (Danish:; 14 August 1777 – 9 March 1851), sometimes transliterated as Oersted ( ), was a Danish chemist and physicist who discovered that electric currents create magnetic fields. This phenomenon is known as Oersted's law. He also discovered aluminium, a chemical element.
DenmarkDenmark is a Nordic country in Northern Europe. It is the metropole and most populous constituent of the Kingdom of Denmark, also known as the Danish Realm, a constitutionallyunitary state that includes the autonomous territories of the Faroe Islands and Greenland in the north Atlantic Ocean. Metropolitan Denmark, also called "continental Denmark" or "Denmark proper", consists of the northern Jutlandpeninsula and an archipelago of 406 islands.
Clipping (morphology)In linguistics, clipping, also called truncation or shortening, is word formation by removing some segments of an existing word to create a diminutive word or a clipped compound. Clipping differs from abbreviation, which is based on a shortening of the written, rather than the spoken, form of an existing word or phrase.
FranceCountry primarily in Western EuropeFrance, officially the French Republic, is a country primarily located in Western Europe. Its overseas regions and territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean.*As an Amazon Associate I earn from qualifying purchases.
