This monograph aims to associate physical concepts covered in high school with technological and scientific applications through basic contents seen in schools. The main concepts are electric current, voltage and resistance, showing the importance of mastering this content, how it was the historical development of electricity and magnetism concept, and also how it was advanced and applied the technologies in the modern world. Thereby building a bridge for the students, which do not associate these facts with their daily life. To do so, simple experiments were performed, in addition a case study during the scientific initiation at the University, showing how this research needs electromagnetic basic theories and how these knowledge are related. Measures were performed with multimeter and DC sources in simple materials with different electrical behaviors. Furthermore, an electronic nose was produced through the thin film deposition technique. The results of the measures associated with the first law of Ohm were discussed, evidencing their presence in the students' daily life. This type of experimental approach has proven effective in schools, as values the learning and interaction among students, since the lack of interest of high school students may be related to only using conventional methods
