Abstract

Imagine a power transistor connected in its common-emitter configuration as shown in the circuit of figure 5.28. By manipulation of the variable resistors R1 and R2, current into the base may be set to any convenient value. If now the resistor R3 is varied over its maximum range to control the positive collector potential, corresponding values of VCE and IC can be recorded. When plotted on a graph, these figures represent a static output characteristic for this transistor. By repeating the experiment for different settings of base current, a whole family of curves can be plotted as shown in figure 7.1.
