The A-C current gain of a transistor is β = 19. In its common-emitter configuration, What will be the change in the emitter current for a change of 0.4 mA in the base-current ?
Text Solution
Verified by ExpertsThe correct answer is:
C
By definition, the 
current gain 
is given by
The emitter - current is the sum of the base- current and the collector-current ( 
)
