: (a) Chapter 1, Section 1.0 to1.3 in the
Grodzinsky text (but you can skip material on Magnetoquasistatics); Read and work examples
1.3.1 to review solutions of Laplace’s Equation (for the electrical potential
Φ
) in spherical
coordinates, which you’ll need for problem 2, and 1.3.2 for additional insights in cylindrical
coordinates.
1. Problem 1.3.3
(Grodzinsky text):
This problem examines the charge, potential, and electric field distribution at the interface
between charged surfaces (e.g., cells, proteins, electrodes, channels in bioMEMs devices, etc.)
and electrolyte solutions (e.g., physiological buffers).
Do parts (a)(d):
Note – analytical
solutions can be found for all answers here. This is one of the most important examples
