Series and parallel combinations
The most complex arrangement series and parallel resistors can sim-
plified into single equivalent resistor combining the separate rules for
series and parallel resistors.6.

By inspection, the circuit contains parallel group consisting R3, and and series
group consisting and series with the equivalent resistor for the parallel branch.5
