Question - In common base mode of 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

Answer: Option B
:
B

I_{b} = I_{e} - I_{c}

= 5.60 - 5.488 = 0.112mA

β = \frac{I_{e}}{I_{b}} = \frac{5.488}{0.112}

= 49.
