Question

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

• A. $\frac{1}{\alpha} = \frac{1}{\beta} + 1$
• B. $\alpha = \frac{\beta}{1 - \beta}$
• C. $\alpha = \frac{\beta}{1 + \beta}$
• D. $\frac{1}{\beta} = \frac{1}{\alpha} - 1$

Hint:

Physics Tip: Because the collector current is always slightly less than the emitter current, $\alpha$ is always slightly less than 1, whereas $\beta$ is usually much larger than 1.

Answer 1

The Correct Option is B
