2.25 Let the BJT of Fig. P2.24 have B,
BR = 5. Moreover, assume that either junction
drops 0.7 V when fully forward biased, regardless
of the BJT's operating mode, and that its forward
current is still zero for a forward bias of 0.65 V or
less. Also, read the hint of Problem 2.24.
(a) If Rc= Rg = 10 kN, R3 = 100 kN, Vcc= 10 V,
and VEr = 0 V, find VRR So that VCE = 1.0 V.
(b) Reconsider the circuit of part (a), but with
VEE = 10 V and Vcc=0 V, and find VBg So that
VEC = 1.0 V.
(c) If Rp = Rc = Rp = 10 kN, VBR = 10 V, and
VEE = 0 V, estimate Vcc so that I= 0.
(d) If R3 = Rc = R; = 10 kN, Vcc = 5 V and
V = 0 V, find VRR so that I, = 1.51p. What is
