Presentation transcript:

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

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

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?
