Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
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.
