[Quiz 4 worksheet questions (*.pdf)]
- Student Learning Outcomes
- Analyze and describe the relationship between the work done on, and changes in the electric potential energy of a moving point charge using energy conservation.
- Understand the relationship between the electric potential energy of a point charge, and the electric potential present at the location of that point charge.
Analyze and describe the electric potential at a specific location, due to several point charges that lie along the same line using the definition of an electric potential for a single point charge, and the principle of superposition.
Understand how electric potentials are visualized for single point charges, dipoles, and other basic charge configurations, and the relationship between electric potentials and electric field lines.
- Understand the relationship between the charges stored in a capacitor versus the electric potential required, and the capacitance.
- Analyze and describe the characteristics of parallel plate capacitors, and the energy that can be stored in a charged capacitor.
- Analyze and describe conventional current as the flow of positive charges per time.
- Analyze and describe emf in an electric circuit as the work done per unit charge by an ideal battery.
- Analyze and describe resistance as the electric potential difference per unit current for an ohmic material ("Ohm's law").
- Analyze and describe circuits using Kirchhoff's rules for flow charge conservation (the junction rule) and for energy conservation (the loop rule).
- Reduce series, parallel, and mixed configurations of resistors and emfs to their appropriate equivalent resistances and emfs, and how Kirchhoff's rules apply differently to series and parallel configurations of resistors and emfs.
