Question

If $\alpha$current gain of a transistor is $0.98$. What is the value of$\beta$-current gain of the transistor?

• A. $4.9$
• B. $49$
• C. $96$
• D. $9.6$

Answer 1

The correct option is B

$49$

Step 1: Given data:

$\alpha$current gain of a transistor is $0.98$.

Step 2: Formula used:

Know that the formula

The value of$\beta$-current the gain of the transistor

$\beta =\frac{\alpha }{\left(1-\alpha \right)}$

Therefore substitute the values in the formula,

$$\begin{gathered} \beta =\frac{0.98}{\left(1-0.98\right)} \\ \beta =49 \end{gathered}$$

Therefore, the value of$\beta$-current the gain of the transistor is $49$.

Hence, the correct option is (B).
