Question: what is the relationship between alpha and beta of a transistor?
Answer: The alpha factor (α) of a transistor is the ratio of its collector and emitter currents (α = Ic/Ie), and it is always less than 1 (between 0.5 and 1). The beta (β) or current gain is the ratio of its collector and base currents (β = Ic/Ib), and it is always more than 1.
