Calculating Power Gain
The power gain of an amplifier is given by the product of voltage gain and current gain. In this case, the voltage gain is 50. To calculate the current gain, we can use the formula:
Current gain = Output impedance / (Output impedance + Input impedance)
Current gain = 200Ω / (200Ω + 1000Ω)
Current gain = 0.1667
Therefore, the power gain can be calculated as:
Power gain = Voltage gain x Current gain
Power gain = 50 x 0.1667
Power gain = 8.333
Converting Power Gain to dB
To convert the power gain to dB, we use the formula:
Power gain (dB) = 10 x log10(Power gain)
Power gain (dB) = 10 x log10(8.333)
Power gain (dB) = 9.33 dB
Therefore, the power gain of the amplifier is 9.33 dB, which is closer to 10 dB than 250 dB. The correct answer should be recalculated.
