QNEET-2017-Ph-967: NEET 2017 Physics - Class 12 NEET-2017-Ph-967 Solution: In a common emitter transistor amplifier the audio signal…
In a common emitter transistor amplifier the audio signal voltage across the collector is 3 V. The resistance of collector is 3 k. If current gain is 100 and the base resistance is 2 k the voltage and power gain of the amplifier is 15 and 200 150 and 15000 20 and 2000 200 and 1000
Multiple Choice Options
- A 15 and 200
- B 150 and 15000
- C 20 and 2000
- D 200 and 1000
Step-by-Step Verified Solution
Given: V i
= 3 V, R C
= 3 k � , R B
= 2 k � ,
_ = 100
Voltage gain of the CE amplifier
A V = _ R c R b = 100 ( 3 2 ) = 150
Power gain = A V _ = 150(100) = 15000
