WebApr 15, 2011 · There are a number of different ways to describe transistor operation. One is to describe the relationship between currents in the different terminals: I c = β I b I c = α I e I e = I b + I c etc. Looking at it this way, you could say that the collector current is controlled by the base current. WebMay 12, 2024 · β (beta), the gain or amplification factor of a transistor, normally is given when solving a circuit equation. However, if it is not given, it can be calculated if the currents, Ib (the base current) and either Ie ( the emitter current) or Ic (the collector current) are known. If Ib and Ic are known, then β can be calculated by the formula: 原神 pc コントローラー
