Question

What are "alpha" and "beta" parameters of a transistor? what is tha relation between the two?​

Answer 1

Answer:

"Alpha" : It is defined as the ratio of collector current to emitter current.

"Beta" : It is the current gain defined as the ratio of collector current to the base current.

The relation between the two is that:

A and B are the parameters for a transistor which defines the current gain in a transistor. A is defined as the ratio of the collector current to the emitter current. B is defined as the current gain which is given by the ratio of the collector current to the base current.

Answer 2

Answer:

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. ... Typically, Beta has a value between 20 and 200 for most general purpose transistors...α and β are the parameters for a transistor which defines the current gain in a transistor. α is defined as the ratio of the collector current to the emitter current. β is defined as the current gain which is given by the ratio of the collector current to the base current...
