Question

For common emitter BJT amplifier if α = 0.98 then what is value of β

🧐 Not the exact question you are looking for?Go ask a question

Solution

The relationship between α and β in a common emitter BJT amplifier is given by the formula:

β = α / (1 - α)

Substituting the given value of α = 0.98 into the formula, we get:

β = 0.98 / (1 - 0.98) = 0.98 / 0.02 = 49

So, the value of β is 49.
