Aplicação dos números complexos na análise de circuitos RLC em corrente alternada senoidal - regime estacionário

Abstract

The present work aims to present theoretical research on the application of complex numbers in the analysis of electrical circuits composed of resistors, capacitors and inductors when subjected to an alternating current source, demonstrating to the reader one of the possible applicability that complex numbers have in modern times characterized by the advancement of technology. For this purpose, through bibliographical research, theoretical references were gathered that include the analysis of circuits using complex numbers. It is worth highlighting the question that will guide this work: what is the applicability of complex numbers in technical and undergraduate courses with an emphasis on Electrical Engineering, Electronics, Mechatronics and Telecommunications. Such questioning becomes important as it refutes the argument of the nonpractical applicability of complex numbers, thus making it a motivating point for their study. Finally, through the presentation of a unique applicability, the aim is to awaken cautious, detailed and dedicated study in the teaching staff and students, refuting the sophism that the theory of complex numbers is too abstruse and futile in applicability.
