"WebKirchhoff's Law and Emissivity. Gustav Robert Kirchhoff (1824–1887) stated in 1860 that “at thermal equilibrium, the power radiated by an object must be equal to the power absorbed .”. This leads to the observation that if an object absorbs 100 percent of the radiation incident upon it, it must reradiate 100 percent. " - Kirchhoff's law in thermodynamics

WebAt thermodynamic equilibrium, nonradiative interactions are balanced, resulting in Kirchhoff’s law of thermal radiation that equals these two properties, i.e., 𝜀=𝛼. For non-equilibrium, Quantum efficiency (QE) describes the statistics of photon emission, which like emissivity depends on both radiative and nonradiative interactions. Web30 mei 2024 · Kirchhoff's current law is thought to describe the translational movement of charged particles through resistors. But Kirchhoff's law is widely used to describe movements of current through resistors in high speed devices. Current at high frequencies/short times involves much more than the translation of particles. Transients …
