Objective(s):
Students should understand the nature of electric fields in and around conductors, so they can:

Explain the mechanics responsible for the absence of electric field inside a conductor, and know that all excess charge must reside on the surface of the conductor.

Explain why a conductor must be an equipotential, and apply this principle in analyzing what happens when conductors are connected by wires.

Students should be able to describe and sketch a graph of the electric field and potential inside and outside a charged conducting sphere.

b) Students should understand the concept of electric potential, so they can:
(1) Determine the electric potential in the vicinity of one or more point charges.
(2) Calculate the electrical work done on a charge or use conservation of energy to determine the speed of a charge that moves through a specified potential difference.
(3) Determine the direction and approximate magnitude of the electric field at various positions given a sketch of equipotentials.
(4) Calculate the potential difference between two points in a uniform electric field, and state which point is at the higher potential.
(5) Calculate how much work is required to move a test charge from one location to another in the field of fixed point charges.
(6) Calculate the electrostatic potential energy of a system of two or more point charges, and calculate how much work is required to establish the charge system.

2. Capacitors

a) Students should understand the definition and function of capacitance, so they can:
(1) Relate stored charge and voltage for a capacitor.
(2) Relate voltage, charge, and stored energy for a capacitor.
(3) Recognize situations in which energy stored in a capacitor is converted to other forms.

b) Students should understand the physics of the parallel-plate capacitor, so they can:
(1) Describe the electric field inside the capacitor, and relate the strength of this field to the potential difference between the plates and the plate separation.
(4) Determine how changes in dimension will affect the value of the capacitance.
