WebKirchhoff's law states that: At thermal equilibrium, the emissivity of a body (or surface) equals its absorptivity. Here, the absorptivity (or absorbance) is the fraction of incident light (power) that is absorbed by the body/surface. In the most general form of the theorem, this power must be integrated over all wavelengths and angles. WebKirchhoffs Laws.

Webmatrix theorem can be extended to directed graphs, see [2, 6] for proofs. According to [2], an early proof of this extension is due to [1], although the result is often attributed to Tutte in [5], and hence referred to as Tutte’s Theorem. The goal of this paper is to provide an elementary proof of Tutte’s Theorem. Most proofs of WebKirchhoff’s Voltage Law: KVL, also called Kirchhoff’s second law, states that the sum of voltages of the closed-circuit loop is zero. If we deﬁne the sign of voltage similar to KCL’s currents case, this law can be as: X y n=1 V n = 0; (7) where V n is each voltage n and y is the number of voltages measured in the closed-circuit loop.
