ABSTRACT
If Vce were to be turned off, then one might expect that all these electrons would go towards +Vb and the base current would increase quite dramatically.
In practice, something else actually happens. This is where the resistance Rb comes into operation. Rb can be deliberately put there by us as an external resistor, or if no external
resistor, may represent the internal resistance of the voltage source Vb. Now, we know that the voltage Vb supplies a voltage drop across the b-e junction of about 0.7 V and the remainder appears across Rb.
