If the base region of a transistor is made large, as compared to a usual transistor, how does it affect (i) the collector current and (ii) current gain of this transistor.

Answer» If the base region of a transistor is made large, then most of the majority charge carriers coming from emitter would get neutralised in the base by the electron-hole combination. As a result of it, only few majority carriers will be reaching the collector. Due to it (i) the collector current will reduce and heance (ii) the current gain will reduce.
