In this work we turn to interdisciplinary as a basis for articulating knowledge from other disciplines with physics, in order to develop the concept of potential difference with pressures. Disciplines such as electronic engineering for low pressure, analysis using theories such as Ohm's Law, Circuit Analysis (Nodal, Meshes, Thevennin and Norton), Kirchhoff Laws, Transducers, Opamp and Transistors, fundamental concepts for technicians and electronic engineers, Mechatronics and telecommunication. We conclude that students receive the knowledge in an easier way when presented in an interdisciplinary way.
