i did this experiment under that topic.........i built a basic transistor amplilfier known as common emitter amplifier and after connecting every thing i was asked to change the tranisistor with a tranistor of exactly the same type and get the value 4 d base, emitter and collector ................on doing this, there was little or no diffrence and i am asked to comment on it

Without a schematic, it's hard to see if there might be something remarkable about the change. Do you have spec's on the two transistors?
