QAIPMT-2011-Ph-1904: NEET 2011 Physics - Class 12 AIPMT-2011-Ph-1904 Solution: A transistor is operated in common emitter configuration at…

A transistor is operated in common emitter configuration at

V_C=2\ \text{V}

such that a change in the base current from

100\ \mu A

300\ \mu A

produces a change in the collector current from 10 mA to 20 mA. The current gain is

Step-by-Step Verified Solution

Current gain, _ = _ I C _ I B = ( 20 _ 10 ) _ 10 _ 3 ( 300 _ 100 ) _ 10 _ 6 = 50
