A transistor has three impurity regions. All the three regions have different doping levels. In order of increasing doping level, the regions are :

When the emitter current of a transistor is changed by 1 mA, its collector current of a transistor is changed by 0.990 mA. The common base circuit current gain for the transistor is :

In case of n-p-n transistor the collector current is always less than the emitter current because :

Transistors are :
