To simplify, a phasor can be defined as a vector used to reproduce a sine wave. It is a very useful mathematical tool, in particular the teaching of alternating current (AC) circuits. However, for the academic calendar to be adhered to, teaching is often carried out after the stages, because is necessary to pressure students to learn how to do math. This dissertation will discuss complex numbers and phasors, explaining from the basic concepts to their applications. It is important to emphasize that the phasor issue is not a trivial matter, and has many details to be fully understood. As the theme is used for practical purposes, its concepts end up being left out. With this work, we intend to build a didactic material capable of guiding, in a clear way and with the necessary theoretical rigor, the study of complex numbers and phasors. Thus, it will serve as a reference for learning and reviewing the theme.
