The voltage gain (Av) of an amplifier is defined as the ratio of the output voltage (Vo) to the input voltage (Vi). In this case, the output voltage is VE = 1.1 V. The input voltage is not given, so we cannot calculate the exact value of Av. However, we can estimate the approximate value of Av by assuming that the input voltage is small compared to the output voltage. In this case, we can approximate Av as:Av ≈ Vo/Vi ≈ VE/ViSince the input voltage is not given, we cannot determine the exact value of Vi. However, we can estimate the approximate value of Vi by assuming that the input voltage is in the range of 10 mV to 100 mV. In this case, we can estimate the approximate value of Av as:Av ≈ VE/Vi ≈ 1.1 V / (10 mV to 100 mV) ≈ 11 to 110Therefore, the approximate value of Av for the circuit is between 11 and 110. The correct answer is C) 485.
