The correct relation between


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

  1. $\beta=\frac{\alpha}{1+\alpha}$

  2. $\alpha=\frac{\beta}{1-\alpha}$

  3. $\beta=\frac{1}{1-\alpha}$

  4. $\alpha=\frac{\beta}{1+\beta}$

Correct Option: , 4



$\alpha=\frac{I_{C}}{I_{E}}, \beta=\frac{I_{C}}{I_{B}}$
