In physics, an electronvolt (symbol eV), also written electron-volt and electron volt, is the measure of an amount of kinetic energy gained by a single electron accelerating through an electric potential difference of one volt in vacuum.

electron volt, unit of energy commonly used in atomic and nuclear physics, equal to the energy gained by an electron (a charged particle carrying unit electronic charge) when the electrical potential at the electron increases by one volt.

In physics, an electronvolt is the amount of kinetic energy required by a single electron accelerating from rest through an electric potential difference of one volt. It is abbreviated as eV. An electron volt is a small unit of energy.

Electonvolt (symbol: eV) is a unit of ENERGY. One eV is equal to the amount of energy one electron acquires by accelerating (from rest) through a potential difference of one volt. It is usually used as a measure of particle energies although it is not an SI (System International) unit.

An electron-volt (eV) is the work required to move an electron through a potential difference of one volt. Alternatively, an electronvolt is equal to the kinetic energy acquired by an electron when it is accelerated through a potential difference of one volt.

2023年7月21日 · One Electron Volt is the amount of energy an electron gains when it is accelerated through an electric potential difference of one volt. It is a convenient unit of measurement when dealing with subatomic particles, where energy values can range from tiny fractions to vast quantities.

2012年2月24日 · One electron – volt is the unit of energy in joules which equals to the amount of work to be done for bringing one electron against an electric field of potential difference 1 volt. This is very tiny or micro unit of energy mainly used for different calculation in atomic and electronic levels.

2024年7月18日 · 1 electronvolt (eV) is equivalent to 1.602 × 10⁻¹⁹ joules, representing the energy gained by an electron when it moves across an electric potential difference of one volt. The fundamental formula to calculate work or energy in Electronvolt (eV) is given by: E = c×v. Electronvolts (eV) as the product of electric charge and voltage.

Electronvolts are a traditional unit of energy, particularly in atomic and nuclear physics. An electronvolt is equal to the energy gained by a single electron when accelerated through 1 volt of electric potential difference.

An electron volt (also written electron-volt and eV) is a unit of energy, specifically the energy that it takes to move an electron through the potential difference of 1 volt (or a proton moving through the same potential difference, in a different direction).
