In short, the vector of currents is a linear transformation of the vector of voltage drops which is itself a linear transformation of the vector of potentials.

(5÷0 no es significativo). Un polinomio es una expresión algebraica que no contiene variables en los denominadores de fracciones y en la que todos los exponentes en cantidades variables son números enteros.
