FIELDS AND POTENTIAL OF OTHER CHARGE DISTRIBUTION
|
| (A) Students should be able to use the principle of superposition to calculate by integration: |
| (1) The electric field of a straight, uniformly charged wire. |
| (2) The electric field and potential on the axis of a thin ring of charge, or at the center of a circular arc of charge |
| (3) The electric potential on the axis of a uniformly charged disk. |
| (B) Students should know the fields of highly symmetric charge distributions, so they can: |
| (1) Identify situations in which the direction of the electric field produced by a charge distribution can be deduced from symmetry considerations |
| (2) Describe qualitatively the patterns and variation with distance of the electric field of oppositely-charged parallel plates. |
| (3) Describe qualitatively the patterns and variation with distance of the electric field of a long, uniformly-charged wire, or thin cylindrical or spherical shell. |
| (4) Derive expressions for electric potential as a function of position in the above cases. |
