1. Chapters 18 & 19 What is the definition of electric potential?
electric potential energy per charge
What will happen if two points in a conductor are at different electric potentials?
charges will move

2. Goals for understanding moving charges in simple circuits:
Know the mathematical definition of electric current
Know what conventional current is
Know what causes and resists electric current (Ohm’s Law)
Know how to calculate the resistance to current in a conductor (such as a wire)
Know how to calculate power for electrical devices

3. Goals for understanding more complicated circuits:
Recognize the two types of circuits: series and parallel
Know the characteristics of each type of circuit:
How does the current through each resistor compare?
How does the voltage across each resistor compare?
How is the equivalent resistance of a group of resistors calculated?
