In common emitter transistor as shown in Fig., the V_(BB) supply can be varied from 0 V to 5.0V. The Si. Transistor has beta_(ac)=250 and R_(B)=100kOmega, R_(c)=1k Omega,V_(C C)=5.0V . Assume that when the transistor is saturated, V_(CE)=0V and V_(BE)=0.8V . Calculate the minimum base current, for which the transistor will reach saturation. Hence, determine V_(i) when the transistor is 'switched on' find ranges of V_(i) for which the transistor is switched off and switched on.
