9.1 Series and Parallel Circuits

• Series Circuits
• There is only a single pathway forcurrent to
  flow
• The sum of the voltages lost on the loads equals
  the total voltagesupplied by the battery
• Current measured anywhere in theseries circuit
  will be the same

• Parallel Circuits
• Multiple pathways for current to flow,adding
  more pathways lowers resistance
• Voltage remains the same through eachpathway of
  the parallel circuit
• Current splits up between the different current
  pathways

So for CURRENT a) in series same
throughout b) in parallel additive among
loads VOLTAGE a) in series additive across
loads b) in parallel same throughout RESISTANC
E a) in series increases with more loads b)
in parallel decreases with more pathways
