    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?


    If the base region is made large, most of the charge carriers coming from the emitter would get neutralised in the base by electron-hole recombination process and this will (i) reduce collector current and hence (ii) reduce current gain.
