The current gains of the semiconductor devices are \[\alpha \]\[=\left( \frac{{{i}_{c}}}{{{i}_{c}}} \right)\]and \[\beta \]=\[\left( \frac{{{i}_{c}}}{{{i}_{b}}} \right)\]The relation between \[\alpha \]and \[\beta \]are:

A) \[\beta =\frac{\alpha +1}{\alpha }\]                              

B) \[\beta =\frac{\alpha }{1-\alpha }\]

C) \[\alpha =\frac{\beta }{1-\beta }\]                  

D) \[\alpha =\frac{1-\beta }{\beta }\]
