Generally speaking, network analysis
is any structured technique used to mathematically analyze a
circuit (a "network" of interconnected components). Quite
often the technician or engineer will encounter circuits
containing multiple sources of power or component
configurations which defy simplification by series/parallel
analysis techniques. In those cases, he or she will be
forced to use other means. This chapter presents a few
techniques useful in analyzing such complex circuits.
To illustrate how even a simple circuit can
defy analysis by breakdown into series and parallel
portions, take start with this series-parallel circuit:
To analyze the above circuit, one would
first find the equivalent of R2 and R3
in parallel, then add R1 in series to arrive at a
total resistance. Then, taking the voltage of battery B1
with that total circuit resistance, the total current could
be calculated through the use of Ohm's Law (I=E/R), then
that current figure used to calculate voltage drops in the
circuit. All in all, a fairly simple procedure.
