For a transistor, the current amplification factor $\alpha$ is $0.8$. If it is connected in common emitter configuration, the change in collector current when the base current changes by $6 \mathrm{mA}$ is

• A

  $6 \mathrm{mA}$
• B

  $4.8 \mathrm{mA}$
• Correct answer
  C

  $24 \mathrm{mA}$
• D

  $8 \mathrm{mA}$

Hence, the correct answer is option: 'C'.
