Definition: The word 'absorptance' in physics refers to the ability of a material or substance to absorb, transmit, and store electrical energy. Specifically, it is the ability of an object or a substance to convert electrical energy into other forms such as heat or light. Absorption is primarily achieved by electrons passing through atoms and molecules, while transmission occurs when electrons are emitted from a conducting surface and absorbed by another surface. The amount of energy that can be stored in an object depends on its efficiency in absorbing and converting energy. In the field of electrical engineering, absorption plays a crucial role in designing power electronics circuits. It is important to understand how to measure and analyze absorption measurements for accurate voltage, current, and power calculations.
