In a common base mode of a transistor, the collector current is 5.488 mA for an emitter current of 5.60 mA. The values of the base - current amplification factor `(beta)` will be :

A

48

B

49

C

50

D

51

Text Solution

Verified by Experts

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