Automating Circuit Analysis with Python: From Ohm’s Law to Complex Networks

Electrical circuit analysis forms the backbone of electrical and electronic engineering. Traditionally performed manually or with commercial simulation software, circuit analysis can now be effectively automated using Python . This article presents a comprehensive guide to circuit analysis automation , starting from basic Ohm’s Law to handling complex multi-loop and multi-node circuits using Python programming . Python offers a flexible, cost-effective, and highly customizable environment for automating both DC and AC circuit analysis. With libraries like SymPy , NumPy , and SciPy , engineers and students can model, solve, and visualize electrical circuits with ease. Introduction to Circuit Analysis Circuit analysis is the process of determining voltage, current, and power in electrical components. It uses principles such as: Ohm’s Law : V = I R V = IR Kirchhoff’s Current Law (KCL) : Sum of currents at a node is zero Kirchhoff’s Voltage Law (KVL) : Sum of voltages in a loop is zero Impedance for AC circu…
