WebJan 2, 2024 · 2 Answers. β is a ratio between the collector and base currents whereas α is also a ratio but between the collector and emitter currents. There is no special … A transistors current gain is given the Greek symbol of Beta, ( β ). As the emitter current for a common emitter configuration is defined as Ie = Ic + Ib, the ratio of Ic/Ie is called Alpha, given the Greek symbol of α. Note: that the value of Alpha will always be less than unity. See more As the Bipolar Transistoris a three terminal device, there are basically three possible ways to connect it within an electronic circuit with one terminal being common to both the input and … See more As its name suggests, in the Common Base or grounded base configuration, the BASEconnection is common to both the input signal AND the output signal. The input signal is … See more In the Common Collector or grounded collector configuration, the collector is connected to ground through the supply, thus the collector terminal is common to both the input and the output. The input signal is connected … See more In the Common Emitteror grounded emitter configuration, the input signal is applied between the base and the emitter, while the output is taken from between the collector and the emitter as shown. This type of configuration … See more

WebJan 28, 2024 · What is current gain alpha and beta? Current gain α is defined as the ratio of collector current to the emitter current at constant collector voltage. Current gain β is defined as the ratio of the collector current to the base current at constant collector voltage. WebThe 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 emitter current (input current). Alpha is calculated using the ... WebJan 28, 2024 · What is current gain alpha and beta?
