MHT CET 2023 14th May Morning Shift | Semiconductor Devices and Logic Gates Question 4 | Physics

For a common emitter configuration, if '$$\alpha$$' and '$$\beta$$' have their usual meanings, the incorrect relation between '$$\alpha$$' and '$$\beta$$' is

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

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

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

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