P114 - Workshop/Recitation Module 4
Current, resistors, DC circuits
Tipler 26-17
Students should visualize the flow of charge (water flow thru pipe analogy is useful)
Dependence of resistance on cross sectional area is the key to this problem
Tipler 26-76
Resistors
Student should know how to find equivalent resistance for resistors in parallel and in series
Tipler 26-91
Kirchoff's laws
Student should be comfortable with making arbitrary choices for current directions to get the problem started
Student should be able to properly use conventions for the sign of voltage drop/rise across EMF's and resistors
Student should be able to pick appropriate closed circuits for voltage sums
Student should be familiar with and able to use concept of solving for N unknowns with N equations
