b. the difference between series and parallel circuits -- particularly, how to calculate currents
c. related to series and parallel circuits -- know how to ascertain relative bulb brightnesses in circuits
11. Regarding the earliest stuff (for the final exam) on charge. Focus on:
a. what the charge concept means
b. electron, proton, neutron, quark
c. Coulomb's law (as an inverse square law)
