Figure 2.9 A comparatively complex circuit showing a number of resistors
in parallel and in series. By breaking the circuit down into groups, the overall
resistance can be calculated
overall resistance. If you can’t do it by calculation you can
always do it by building the circuit up on breadboard and
measuring it. Resistor and multi-meter tolerances, of course,
will mean the measured result may not give exactly the same
result as the calculated one.
Meanwhile, there’s always the quiz over the page to keep
you occupied!
