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

Options:

Answer:

Solution:

$I_{c} = 5.488 mA, I_{e} = 5.6 mA$ $α = \frac{I _{c}}{I _{e}}$ $α = \frac{5.488}{5.6}$ $β = \frac{α}{( 1 - α )} = 49$
