The
second
circuit
Figure 2.4 shows the next circuit we're going to look at
and how to build it on breadboard. It's really just an-
other simple circuit, this time consisting of two resistors
in a line — we say they're in
series.
The aim of this ex-
periment is to measure the overall resistance of the
series
resistors and see if we can devise a formula which
allows us to calculate other series resistors' overall resis-
tances without the need of measurement.
Figure 2.5 shows the more usual way of representing a
circuit
in a drawing — the
circuit
diagram.
What we have
done is replace the actual resistor shapes with
symbols.
