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. Assume air resistance is negligible unless otherwise stated.

III. In all situations, positive work is defined as work done on a system. IV. The direction of current is conventional current: the direction in which

positive charge would drift. V. Assume all batteries and meters are ideal unless otherwise stated.
