The knowledge of the characteristics of a transistor is a
prerequisite for a deeper understanding of the processes related to
a transistor amplifying or switching stage. Of the four
characteristics (the output, control, input and reverse voltage
transfer ratio characteristics), the output and control
characteristics are particularly important. This experiment is
therefore limited to the recording of the characteristic curves for
control and output. The other characteristic curves can be
determined by slightly altering the experimental setup.
We recommend some class time to be spent after the
experiment going over the characteristic curves that the students
recorded. The operating lines graphed in the output characteristic
field can be used to deepen their understanding of the control
process. For example, you can explain voltage gain as a function of
load resistance, the oppositional nature of output and input
voltage, the output power achievable, and the influence of the
position of the operating point on signal clippings.
