Provides a simple routine which allows first-year physics students to use programmable calculators to solve otherwise complex electrostatic problems. These problems involve finding electrostatic potential and electric field on the axis of a uniformly charged ring. Modest programing skills are required of students. (DH)

Describes a method of network analysis that allows avoidance of Kirchoff's Laws (providing the network is symmetrical) by reduction to simple series/parallel resistances. The method can be extended to symmetrical alternating current, capacitance or inductance if corresponding theorems are used. Symmetric cubic network serves as an example. (JM)

Describes an experiment undertaken to determine what relative electric charges would result if three or more pieces of transparent tape were placed on top of each other and then separated one at a time. Makes suggestions for using the project in high school and undergraduate classes. (WRM)

Derives the current in the wire joining two points when n points are joined two by two by wires of equal resistance, and two of them are connected to the electrodes of a battery of electromotive force E and resistance R. (YP)

Describes a study of three parts: (1) the application of a statistical technique for predicting performance; (2) a computer program for teaching basic problem-solving skills; and (3) evidence for the value of teaching with complex homework problems in an introductory physics course required for engineering majors.
