Question

In a common base mode of a transistor, the collector current is 5.488 mA for an emitter current of 5.6 mA . The value of the base current amplification factor ( $\beta$ ) will be

Professor PC Thomas Classes · Answer

$I_E = I_B + I_C \Rightarrow I_B = 5.6 - 5.488 = 0.112$ mA. $\beta = \frac{I_C}{I_B} = \frac{5.488}{0.112} = 49$.
