Four study segments of the Self-Paced Physics Course materials are presented in this sixth problems and solutions book used as a part of student course work. The subject matter is related to electric currents, current densities, resistances, Ohm's law, voltages, Joule heating, electromotive forces, single loop circuits, series and parallel circuits, Kirchhoff's rules, ammeters, galvanometers, potentiometers, and Wheatstone Bridges. Contained in each segment are an information panel, core problems enclosed in a box, core-primed questions, scrambled problem solutions, and true-false questions. Study guides are provided to answer the true-false questions and to reveal directions for reaching solutions. When the core problem is answered incorrectly, the study guide requires students to follow the remedial or enabling loop, leading to the solutions of core-primed questions. Also included is a sheet of problem numbers with corresponding page numbers which locate correct answers. (Related documents are SE 016 065 - SE 016 088 and ED 062 123 - ED 062 125.) (CC)
