As we have learnt,

 

Relation between emitter current ,Base current,collector current -

I_{E}= I_{B}+I_{C}
 

- wherein

I_{E}=Emitter\: Current

I_{B}= Base \: Current

I_{C}= Collector \: Current

 

 I_C = 5.488 mA

I_E = 5.60mA

I_B = 0.112mA

Current amplification factor

\beta = \frac{\Delta I_C}{\Delta I_B} = \frac{5.488}{0.112} = 49

 


Option 1)

48

Option 2)

49

Option 3)

50

Option 4)

51
