Watt-hours (Wh)
Definition
A watt-hour (Wh) is a unit of energy equal to the work done by one watt of power sustained for one hour. It equals 3,600 joules.
History
The watt-hour emerged with the development of electrical power systems in the late 19th century. It provided a practical way to measure and bill for electrical energy consumption.
Current use
Watt-hours are used for small battery capacities (e.g., phone batteries, portable electronics) and as a base unit for kilowatt-hours used in household electricity metering.
Electronvolts (eV)
Definition
An electronvolt (eV) is a unit of energy equal to the amount of kinetic energy gained by a single electron when accelerated through an electric potential difference of one volt. It equals approximately 1.602 × 10⁻¹⁹ joules.
History
The electronvolt emerged in the early 20th century with the development of particle physics and quantum mechanics. It provided a practical unit for describing atomic and subatomic energy scales.
Current use
Electronvolts are the standard unit in particle physics, nuclear physics, semiconductor physics, and quantum chemistry for expressing binding energies, photon energies, and particle masses.
