WebTo calculate beta, use the following formula : β= ΔI BΔI C. The current gain in the common-base circuit is calculated in a method similar to that of the common emitter except that the input current is I E not I B and the term Alpha (α) is used in place of beta for gain. Alpha is the relationship of collector current (output current) to ... 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. If the β of the transistor is known, α can be calculated very easily by the formula: Example.
