A 22 mV signal is applied to the base of a properly biased transistor that has an r'e = 7 ▲ and an RC = 1.2 k▲. The output voltage at the collector is
A)17.1 V.
B)3.77 V.
C)22 mV.
D)7 V.

Question

Quizplus · Accepted Answer

The output voltage can be calculated using the formula Vout = Vin * (RC / r'e), where Vin is the input voltage, RC is the collector resistor, and r'e is the emitter resistance. Substituting the given values: Vout = 22mV * (1200 / 7) = 3.7714V, which rounds to 3.77 V.
