Junction Transistor

In the case of common emitter transistor amplifier, the ratio of collector current to emitter current is 0.96, then the current gain $(\beta)$ of the amplifier is

Show answer and solution

Answer: (c)

$\alpha = \dfrac{I_C}{I_E} = 0.96$
$\beta = \dfrac{\alpha}{1 - \alpha} = \dfrac{0.96}{0.04} = 24$
So the answer is (c) 24.
