This paper presents a classroom project based on the War of Currents to explore fundamental electrical engineering concepts such as RMS value, source superposition, discrete Fourier transform, electronics, and programming. The dynamic temperature response of an electrical resistor subjected to DC, AC, triangular, and square voltages with the same RMS value is analyzed. Signals are processed using the discrete Fourier transform to calculate power, and circuits are simulated in OpenModelica. The power supplied by the voltage sources is validated using the source transformation theorem. Additionally, Arduino and a temperature sensor are integrated, combining electronics with microcontroller programming. The experiment involves heating the resistor with each type of voltage until thermal saturation is reached. The objective is to demonstrate that the resistor's thermal response remains consistent when the RMS value is maintained across different signals. This project is expected to help electrical engineering students and related fields gain a deeper understanding of these concepts by integrating various undergraduate topics.
