Question

For a transistor, the current ratio α D C ​ = 70 69 ​ . The current gain β D C ​ is

TestHub · Accepted Answer

The relationship between the current ratio $α_{D C}$ and the current gain $β_{D C}$ is given by the formula:

$β_{D C} = \frac{α _{D C}}{1 - α _{D C}}$

Given $α_{D C} = \frac{69}{70}$ , substituting this value into the formula gives:

$β_{D C} = \frac{\frac{69}{70}}{1 - \frac{69}{70}}$

$β_{D C} = \frac{\frac{69}{70}}{\frac{1}{70}}$

$β_{D C} = 69$

Answer: $69$
