This book "BASIC ELECTRIC CIRCUITS" is a result of our lectures which we collected after teaching the material to first and second year engineering and science students over many years, the material is presented to students in a very simple way so that an average student will easily understand and grasp the material. Although the book is intended mainly to first/second year electrical engineering students, the book is also very beneficial to science students specializing in physics, math and chemistry presented in a step-by-step teaching approach. The book included all necessary equations derivations for different subjects, also it includes all experimental data and full data analysis by employing computations and graphics when needed. The material presented in the book includes, source internal resistance and loading problem, network analysis I (the superposition principle and Kirchhoff’s Laws), Network analysis II (Norton and Thevenin methods, DC driven RC circuit, DC driven RL circuit, DC driven LC circuit, DC driven RLC circuit, AC driven RC, RL, LC circuits, AC driven RLC circuit, Resonance and anti-resonance, Low pass filters, High pass filters and Band pass filters. The book also includes appendices which discusses error propagations, least square fit method and how to use the instruments like the oscilloscope, signal generator and multimeters.
