Kilowatt-Second
A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.
History/Origin
The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.
Current Use
Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
