The current gain of the cb transistor is
WebCurrent gain in the common emitter circuit is obtained from the base and the collector circuit currents. Because a very small change in base current produces a large change in collector current, the current gain (β) is always greater than unity for the common-emitter circuit, a typical value is about 50.

WebMar 15, 2024 · The current gain for a CB configuration is called Alpha, ( α ). In a BJT amplifier the emitter current is always greater than the collector current as IE = IB + IC, the current gain ( α) of the amplifier must therefore be less than one (unity) as IC is always less than IE by the value of IB.
