In a common base mode of a transition , the collector current is `5.488 mA` for an emitter currect of `5.60 mA` . The value of the base current amplification factor `(beta)` will be

A

50

B

51

C

48

D

49

Text Solution

Verified by Experts

The correct Answer is:
D
`alpha=I_c/I_e=(5.488)/(5.60)=0.98`
`beta=(alpha)/(1-alpha)=(0.98)/(1-0.98)=49`
