Electrokinetics - Reminders and Answers

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.
