The value of $β$ of a transistor is 19. The value of $α$ will be

Options:

Answer:

Solution:

$I_{E} = I_{B} + I_{C}$

$\Rightarrow \frac{I_{E}}{I_{C}} = \frac{I_{B}}{I_{C}} + 1$

$\Rightarrow \frac{1}{α} = \frac{1}{β} + 1 = \frac{1}{19} + 1$

$\Rightarrow \frac{1}{α} = \frac{20}{19}$

$\Rightarrow α = \frac{19}{20} = 0.95$
