Volt Ampere
Volt ampere (V·A) is a unit of apparent power in an electrical circuit, representing the product of voltage and current without considering power factor.
History/Origin
The volt ampere was established as a unit of apparent power with the development of electrical engineering, particularly as a measure in alternating current (AC) systems. It is derived from the SI units volt (V) and ampere (A).
Current Use
Volt ampere is used to quantify apparent power in AC electrical systems, especially in the context of transformers, generators, and power supplies, to assess capacity and performance.
Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
