This document discusses the relationship between electric current and potential difference. It defines potential difference as the work done to move one coulomb of charge between two points. It states that the potential difference across a metallic conductor is directly proportional to the current through it when temperature and other conditions are constant, known as Ohm's Law. The objectives are for students to understand this relationship, state Ohm's Law, and solve problems involving potential difference, current and resistance.
