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 (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
