Complex Resistor Combinations
Most circuits use both
series and parallel
wiring such as
electrical wiring in a
Example of Typical
Household Circuit 
Outlets are wired in
parallel to allow
appliances to operate
If one appliance is
switched off, the others
stay on
Wiring in parallel ensures
that an identical
potential difference
exists across any
To prevent excessive
current, a fuse or
circuit breaker must be
placed in series with all
the outlets.
A circuit breaker
triggers a switch that
interrupts the current
when current reaches a
certain value.
Simplify circuit into groups of series and
parallel resistors.
Find Req for each group using appropriate
Sample Problem 20C
