In the circuit shown in the figure, the input voltage Vi is 20 V, VBE = 0 and VCE = 0. The values of IB, IC and β are given by
IB = 40 μA, IC = 10 mA, β = 250
IB = 25 μA, IC = 5 mA, β = 200
IB = 40 μA, IC = 5 mA, β = 125
IB = 20 μA, IC = 5 mA, β = 250
C.
IB = 40 μA, IC = 5 mA, β = 125
VBE = 0,
Vi = 20 V
VCE = 0
Vb = 0 (earthed)
Ic =
Or
Vi = 0 + IBRB
