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

49

B

50

C

51

D

48

Text Solution

Verified by Experts

The correct Answer is:
A
`beta=(I_(C))/(I_(B))=(5.488xx10^(-3))/((5.6-5.488)xx10^(-3))=49`
