Szukana fraza: [Abstrakt = "The paper presents the original matrix method developed for the circuits analysis of current AC in in the record of complex numbers. This method describ electrical circuits by of the developed impedance matrix and of the developed electromotive forces vector .The impedance matrix and the vector of electromotive forces in the described form of matrix equation they contain of branch currents. The calculated values of the branch currents of the electric circuit using the developed matrix method were compared with the values of the currents determined by Maxwell's loop current method. The same values of branch currents were obtained. In addition, the developed matrix method was used to calculate the power and electric energy respectively branch and total. Calculations of the above\-mentioned electrical values of the circuit were carried out in the environment of the Mathcad numerical program."]
