Conductors in Electrostatic Equilibrium
(Be sure you understand where and how each goal in each assignment applies to our
homework, discussion, lecture, and lab activities.)
Use Gauss' law along with basic mechanics and electrostatics principles to deduce the
presence or absence of electric fields and electric charge in, on, or near conductors in
Draw electric field lines in the vicinity of conductors in electrostatic equilibrium, and use the
geometry of those lines to determine relative electric field strengths at different locations.
Use the Method of Image Charges to determine the magnitude and direction of the electric
field due to electric charges near a conducting plane.
Use the relationships between electric charge and electric fields to explain and calculate the
strengths of electric effects in physical phenomena discussed in lecture and your textbook.
Show how to determine voltage (electric potential difference) from electric field and vice-
versa using line or path integrals or space derivatives along with equations or graphs.
Determine the electric current, current density, electric field, voltage, resistivity, drift
velocity, or geometry in current-carrying conductors, given appropriate other quantities.
Conceptually translate an equation for electric field or potential difference
as a function of position into a graph (without doing detailed numerical calculations).
Show that your algebraic and numerical results have the correct units.
Show that your algebraic and numerical results are physically reasonable.
