In a common-base of 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 (2) 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`
