The following conventions are used in this exam. I. The frame of reference of any problem is assumed to be inertial unless otherwise stated. II. In all situations, positive work is defined as work doneona system. III. The direction of current is conventional current: the direction in whichpositive charge would drift. IV. Assume all batteries and meters are ideal unless otherwise stated. V. Assume edge effects for the electric field of a parallel plate capacitorunless otherwise stated. VI. For any isolated electrically charged object, the electric potential is defined as zero at infinite distance from the charged object.
