Question
In a common-base connection, the emitter current is 6.28 mA and the collector current is 6.20 mA. Determine the common-base DC current gain.
Solution
Data : The emitter current is IE = 6.28 mA.
The collector current is IC = 6.20 mA
`alpha_"dc" = "I"_"C"/"I"_"E"`
`=> alpha = 6.20/6.28`
`=> alpha = 0.987`
The common base DC current gain is 0.987.
