In a transistor, doping level in base is increased slightly. How Will it affect (i) collector current (ii) base current?

Dear student
If doping level of base is increased, the resistivity of the base will reduce. As a result the base current (IB) will increase.

Since, IE = IB + IC

Thus, the collector current (IC) will decrease. Consequently the current gain of the transistor, IC/IB will decrease.

If doping level in base is increased slightly then ,
its collector current decreases slightly and its base current increases slightly ..
