Bjt alpha and beta

WebApr 2, 2024 · Define $\alpha $ and $\beta $ in terms of the collector current, base current and emitter current. Define mathematical expression giving relation between $\alpha $ and $\beta $. The emitter current is equal to the addition of collector current and base current. Using these relations, find the required answer. 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 ...
