NEET 2017 Physics Transistor Amplifier MCQ Question
Type: MCQ-numerical-Medium-Class 12
In a common emitter transistor amplifier, the audio signal voltage across the collector is 3 V. The resistance of collector is 3 kΩ. If current gain is 100 and the base resistance is 2 kΩ, the voltage and power gain of the amplifier is
A
200 and 1000
B
15 and 200
C
150 and 15000
D
20 and 2000
Correct Answer
Option C
Detailed Explanation
The voltage gain is given by the ratio of collector resistance to base resistance multiplied by current gain. Power gain is voltage gain times current gain.
