1. Comparing Series and Parallel Circuits

2. Series vs. Parallel Series Parallel Compare: Current Flow
Potential Difference across resistors
Total resistance of circuit and how it affects current flow

3. Series vs. Parallel Comparing Voltage

V = 12V
8 Volts
V = 12V
12 Volts
R= 2
R=4 
R1=4
R2= 2
4 Volts
Compare the potential difference across the resistors/lamps
V = IR

4. Series vs. Parallel Comparing Resistance
V = 12V
V = 12V
R= 2
R=4 
R1=4
R2= 2
RT = = 6
1/RT = 1/4 + 1/2 = 1.3 
Compare the Total Resistance of the circuits

5. Series vs. Parallel Comparing Current
