En savoir plus
This book offers a progressive, operational overview of electrokinetics: from charge carriers (electrons, holes, ions, plasma) to the macroscopic laws that govern real circuits. After reviewing the fundamental quantities (current, current density, electric field) and energy balances (Joule effect, power, efficiency), the text bridges the gap between the microscopic and macroscopic forms of Ohm's law, while clarifying the role of resistivity, conductivity and mobility. Kirchhoff's laws are treated systematically (nodes, meshes, direction of travel), then applied to the analysis of series/parallel groupings of resistors, generator/receiver models (emf, internal resistance) and RC transients (time constant, charge/discharge, 63%/99% criteria). Each chapter concludes with fully-corrected exercises geared to solving problems and verifying orders of magnitude, to provide students and engineers with tools that can be immediately reused in the laboratory, in simulation and in examinations.
