Simulation and Analysis of Resistive-Capacitive (RC) Circuits

This paper investigates the implementation of a resistor-capacitor (RC) circuit simulation using the C++ programming language, focusing on the capacitor charging process in a first-order transient response. The primary aim is to reinforce theoretical understanding through practical computational modelling and visualization. The simulation employs numerical methods to calculate voltage variations across the capacitor over time, allowing dynamic observation of the circuit’s behaviour. To enhance comprehension, the results are visualized using GNUplot, generating clear and exportable graphs that illustrate the transient response in a user-friendly format. The findings indicate that the simulated results closely align with theoretical predictions, confirming the accuracy and reliability of the computational model. Furthermore, visualizing the charging process provides an intuitive understanding of RC circuit dynamics, bridging the gap between abstract theory and practical application. This approach demonstrates the educational value of integrating programming and graphical tools in electrical engineering teaching, highlighting how hands-on simulations can strengthen conceptual learning. Overall, the manuscript supports the notion that combining numerical modelling with visual representation enhances both engagement and mastery of fundamental electronic circuit concepts.
