For a common emitter configuration, if ' $α$ ' and ' $β$ ' have their usual meanings, the incorrect relation between ' $α$ ' and ' $β$ ' is

Options:

Answer:

Solution:

$β = \frac{I _{B}}{I _{C}} and α = \frac{I _{C}}{I _{E}}$ $∴ \frac{1}{α} = \frac{I _{B} + I _{C}}{I _{C}} \Rightarrow \frac{1}{α} = \frac{1}{β} + 1 ∴ \frac{1}{α} - 1 = \frac{1}{β} \Rightarrow α = \frac{β}{β + 1}$
