A) \[\beta =\frac{1-\alpha }{\alpha }\]
B) \[\beta =\frac{\alpha }{1-\alpha }\]
C) \[\beta =\frac{\alpha }{1+\alpha }\]
D) \[\beta =\frac{1+\alpha }{\alpha }\]
Correct Answer: B
Solution :
As we know \[{{i}_{E}}={{i}_{C}}+{{i}_{B}}\] \[\Rightarrow \frac{{{i}_{e}}}{{{i}_{c}}}=1+\frac{{{i}_{b}}}{{{i}_{c}}}\]\[\Rightarrow \frac{1}{\alpha }=1+\frac{1}{\beta }\]\[\Rightarrow \beta =\frac{\alpha }{1-\alpha }\].
