Questions
In a common emitter transistor amplifier the audio signal voltage across the collector is 3 V. The resistance of collector is 3 . If current gain is 100 and the base resistance is 2, the voltage and power gain of the amplifier is
detailed solution
Correct option is B
Given: Vi=3 V,RC=3kΩ,Rp=2kΩ, β=100Voltage gain of the CE amplifier, AV=-βacRCRB=-10032=-150Power gain, AP=β×AV=100×(-150)=-15000Negative sign represents that output voltage is in opposite phase with the input voltage.Talk to our academic expert!
