QAIPMT-2009-Ph-2142: NEET 2009 Physics - Class 12 AIPMT-2009-Ph-2142 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

200\ \mu A

produces a change in the collector current from 5 mA to 10 mA. The current gain is

Step-by-Step Verified Solution

Current gain, _ = _ I C _ I B = ( 10 _ 5 ) _ 10 _ 3 ( 200 _ 100 ) _ 10 _ 6 = 50
