Question

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

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (C)

The correct options are
A

C

$I_e=I_b+I_c\frac{I_e}{I_c}=\frac{I_b}{I_c}+1\frac{1}{\alpha }=\frac{1}{\beta }+1$
Or
$\alpha =\frac{1}{1+\beta }$
