Volumes have been written on transistor biasing, but Figure 10.45 gets at the main idea. Suppose that Vbe = 1.5 V and that the "input" produces its own voltage, 0.1 V sin(ωt). The total resistance is 10 Ω in the input loop, which goes clockwise from the emitter through the various components to the base, then back to the emitter through the base-emitter diode. This diode is forward biased, with the base at all times 0.7 V higher than the emitter. Suppose also that Vce = 12V and that the "output" is 350 O. Now, given that for every 201 electrons entering the emitter, 1 passes out the base and 200 out the collector, calculate the maximum and minimum in the sinusoidally varying (a) current in the base-emitter (input) circuit, (b) power delivered by the "input," (e) power delivered to the "output," and (d) power delivered by Vce. (e) What "does most of the work?
