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

51

B

48

C

49

D

50

Text Solution

Verified by Experts

The correct Answer is:
C

For a common base transistor amplifier, `alpha=I_C/I_E=5.488/5.60`=0.98
`therefore beta = alpha /(1-alpha)=0.98/(1-0.98)` = 49
