The formula to calculate the Current Amplification Factor is:
\[ \alpha = \frac{\beta}{\beta + 1} \]
Current Amplification Factor in a BJT transistor is defined as the ratio of output current to its input current.
Let's assume the following value:
Using the formula:
\[ \alpha = \frac{2.5}{2.5 + 1} = 0.714285714285714 \]
