[edit] Electrostatics
Electric field above a line charge
- What is the field above the center of a finite line charge? Above one end? Above an infinite line charge?
- There is a dipole in the z-direction. What is the field at some point r from the center of the dipole?
Capacitance of two Circular Shells
- Given two concentric spherical shells with charge q+, q- and radii r1, r2 respectively, what is their capacitance?
- Can you derive other useful equations from Maxwells equations? Do you know how to use the formulas correctly?
Potential of two Infinite Conducting Sheets
- You have two infinitly conducting sheets in the x, y plane. One runs along y=0, and the other at y=x. What is the potential between the two sheets?
[edit] Circuits
- Given some initial conditions, solve for the time-dependence of the charge for a simple LC circuit.
[edit] Magnetostatics
- What is the magnetic field above a finite wire? Infinite wire?
Magnetic field due to ring of current
- What is the magnetic field due to a ring of current along the axis that is perpendicular and goes through the center of the ring?
