Question

$\text { Figure } 17 < 1$
-If the collector-to-emitter voltage is about 0 V in Figure 17-1, the possible trouble is ________.
A)the amplifier is saturated 
B)the amplifier is cut off 
C)this is a normal condition 
D)the transistor is open

Quizplus · Accepted Answer

If the collector-to-emitter voltage is about 0 V, it means that the transistor is in saturation, which occurs when the collector current reaches its maximum allowable value. This can be caused by a too high voltage input signal or a too low base resistor value, leading to an excessive base current. Therefore, the best choice is A: the amplifier is saturated.
