The Physics 3 Tutor (Electricity & Magnetism): Learning By Example DVD Series teaches students about physics through example problems that progressively grow more difficult. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned are committed to long term memory. This episode covers the electric potential of a dipole and continuous charge distributions. Students will learn how the electric potential applies to dipoles and charge distributions and why it is important. Grades 9-College. 53 minutes on DVD.
