PHY481 - Lecture 10: The image charge method
Griths: Chapter 3
A key property of electric elds and potentials in electrostatics is that of uniqueness, which means that if we
nd a solution that satisies the boundary conditions, then the solution is uniqu

PHY481 - Lecture 11: Solutions to Laplaces Equation
Griths: Chapter 3
Continuing from Lecture 10, we noted that the solution to a charge placed outside a grounded conducting sphere
may be written as,
V (r R, ) =

Review of dielectric and magnetic materials
Dielectric properties of materials are due to atomic-scale electric dipoles. Atoms and molecules have induced dipoles
so that when an electric eld is applied they have a dipole moment. Often the response is li

PHY481 - Lecture 12: Solutions to Laplaces equation
Griths: Chapter 3 Before going to the general formulation of solutions to Laplaces equations we will go through one more very important problem that can be solved with what we know, namely a conducting
