In the circuit shown in the figure , the input voltage `V_i` is 20 V, `V_BE`=0V and `V_CE`=0V. What are the value of `I_B,I_C,beta`?

Text Solution

Verified by Experts

`I_B=(V_i)/(R_B)=(20V)/(500kOmega)=40muA[:.V_(BE)=0V]`
`I_C=(V_CC)/(R_C)=(20V)/(4kOmega)=mA[:.V_CE=0V]`
`beta=(I_C)/(I_B)=(5mA)/(40muA)=125`
