Question

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

• A. 0.49
• B. 49
• C. 4.9
• D. 5

Answer 1

The correct option is B 49

Given : $\alpha =0.98$

Current gain $\beta =\frac{\alpha }{1-\alpha }$

$\therefore$ $\beta =\frac{0.98}{1-0.98}=49$
