QNEET-2016-Ph-1158: NEET 2016 Physics - Class 12 NEET-2016-Ph-1158 Solution: For CE transistor amplifier the audio signal voltage across the …
For CE transistor amplifier the audio signal voltage across the collector resistance of 2 k is 4 V. If the current amplification factor of the transistor is 100 and the base resistance is 1 k then the input signal voltage is 10 mV 20 mV 30 mV 15 mV
Multiple Choice Options
- A 10 mV
- B 20 mV
- C 30 mV
- D 15 mV
Step-by-Step Verified Solution
Voltage gain, A = _ R C R B = 100 _ 2000 1000 = 200
Also, A = V 0 V i
_ V i = V 0 A = 4 200 = 20 mA
