If you have the value of the emitter current of a transistor circuit and you want to solve for the collector current, the emitter current is multiplied by α to give the collector current. The formula for α is ...

WebApr 11, 2024 · 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). Since a given transistor may be connected in any of three basic configurations, there is a definite relationship, as pointed out earlier, between alpha ( a ), beta ( b ), and gamma ( g ).

Webα (Alpha), the factor by which emitter current is multiplied to yield collector current, can be calculated in two ways. 1st Way to Calculate Alpha α.
