In a common base mode of a transistor, the collector current is 5.488 mA for an emitter current of 5.60 mA . The value of the base current amplification factor (β) will be:

Solution & Step-by-step Explanation

Given I_{c} = 5.488 mA and I_{e} = 5.60 mA .Current gain in common base mode α = \frac{I _{c}}{I _{e}} = \frac{5.488}{5.60} = 0.98 .The relation between α and β is: β = \frac{α}{1 - α} β = \frac{0.98}{1 - 0.98} = \frac{0.98}{0.02} = 49
