About these units
Watt-hour
A Watt-hour (Wh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One Watt-hour is equivalent to one watt of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For instance, a 100-watt light bulb running for 10 hours consumes 1000 watt-hours, or 1 kilowatt-hour (kWh). Watt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
Joules
The Joule (J) is the SI unit of energy. One joule is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter. It can also be defined as the energy transferred when one watt of power is applied for one second. The joule is a versatile unit used in various scientific and engineering contexts to measure energy, work, and heat. It is commonly used in physics, chemistry, and engineering to quantify the energy content of fuels, the work done by machines, and the energy used or produced in electrical circuits.
