Question

A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased. This transistor can be used as a power amplifier because A. the output current will be much smaller than the input current. B. the output voltage will be much larger than the input voltage. C. the output current will be much larger than the input current. D. the output voltage will be much smaller than the input voltage.

Answer 1

the output current will be much larger than the input current

Step-by-step explanation:

Answer 2

So we want to know why can a PNP transistor be used as a power amplifyer. Transistors are devices that can amplify the voltage of an input signal. Since P=V*I where V is the voltage and I is the current, if we increase the voltage V we see that power P must increase. So the correct answer is B. the output voltage will be much larger than the input voltage.
