Q. If $\alpha\ and\ \beta$ are the collector emitter short circuit current amplification factor and collector base short circuit current amplification factor respectively of a transistor then $\alpha$ is equal to
A) $\frac{1 + \beta}{\beta}$
B) $\frac{\beta}{1 - \beta}$
C) $\frac{1 - \beta}{\beta}$
D) $\frac{\beta}{1 + \beta}$
Explanation
(d) Relation between $\alpha\ and\ \beta\ $is given by,
$\beta = \frac{\alpha}{1 - \alpha}$ or $\alpha = \frac{\beta}{1 + \beta}$
