Figure 2-15. Conductance/Resistance Conversion
You may encounter situations where conductance is more convenient to
measure than resistance. For example, the resistance of a photodiode is
inversely proportional to the available light, i.e. as light increases, resistance
decreases. This might be confusing if you want to examine the response of
the component over a range of values. However, since conductance is the
reciprocal of resistance, photodiode conductance is directly proportional to
available light. As light increases, conductance increases. It might be easier
to examine the photodiode response in terms of conductance, and then covert
the measurements to resistance values if desired.
