The correct relation between \( \alpha \) (ratio of collector current to emitter current) and \( \beta \) (ratio of collector
P current to base current) of a transistor is:

W
(1) \( \beta=\frac{\alpha}{1+\alpha} \)
(2) \( \alpha=\frac{\beta}{1-\alpha} \)
(3) \( \beta=\frac{1}{1-\alpha} \)
(4) \( \alpha=\frac{\beta}{1+\beta} \)
