Determine IR, Ic and VCE in
the following circuit.
Step 1: Solve for Ig.
Step 2: Solve for Ic.
Vcc – VBE
Ic = BIB
Ic = 90(11.91µA)
Ic = 1.07MA
+10v
IR =
RF + B(Rc + RE)
10v – 0.7v

IB =
250kN + 90(4.7kN + 1.2kN)
IB = 11.91HA

Step 3: Solve for VCE-
VIN
VCE = Vcc - Ic(Rc + Rg)
VCE = 10v – 1.07mA(4.7kN + 1.2kN)
Vce = 10v – 6.31v
