The constant `alpha` of a transistor is 0.9 .What would be the change in the collector current corresponding to a change of 4 mA in the base current in a common emitter arrangement?

Explanation

To solve the problem step by step, we will use the relationship between the base current (Ib), collector current (Ic), and the transistor's alpha (α) and beta (β).

### Step 1: Understand the relationship between alpha and beta
The relationship between alpha (α) and beta (β) for a transistor is given by the formula:
\[ \beta = \frac{\alpha}{1 - \alpha} \]
where:
