What is the circuit value of Av?

Quizplus · Accepted Answer

The voltage gain (Av) of a common-emitter amplifier is approximately given by the formula Av = -RC/RE. Substituting the given values, Av = -3.3 kΩ / 1.5 kΩ = -2.2. However, considering the load resistance (RL) and the internal resistance of the transistor, the effective gain is increased, leading to a value closer to 102.
