Question:

For a transistor, the current amplification factor is 0.8. The transistor is connected in common emitter configuration. The change in the collector current when the base current changes by 6 mA is

Options:

6 mA

4.8 mA

24 mA

8 mA

Correct Answer:

4.8 mA

Explanation:

Given that,

$β = 0.8$

$ΔI_b = 6 mA$

$ΔI_c = βΔI_b$

$∴ΔI_c = 0.8 × 6 mA = 4.8 mA$
