PHYS345 Electricity and Electronics

Series and Parallel Combinations
Two resistors in series
Resistors R1 and R2 are in series; one end of each is connected, with nothing else at junction. Same current flows through each resistor.
  R1 and R2 are not in series
R1 and R2 are NOT in series!
Two resistors in parallel
Resistors R2 and R3 are in parallel; ends of both are directly connected to each other, with nothing between. Same voltage difference across each resistor.
  R2 and R3 are not in parallel
R2 and R3 are NOT in parallel!
(or in series either.)
