WebNov 7, 2024 · Kirchhoff’s First Law. Kirchhoff’s first law states that at any node (junction) in a circuit, the sum of currents passing into that node is equivalent to the total of currents flowing out of that node. This means that if we think of a node as a water tank, the water flow speed filling the tank is equal to the one emptying it.

The goal of this paper is to introduce a local form of Kirchhoff law to model light emission by nonequilibrium bodies. While absorption by a finite-size body is usually described using the absorption cross section, we introduce a local absorption rate per unit volume and also a local thermal emission rate per unit volume. parole incrociate gratis
