A voltage divider like that in Fig. 3.13 is to be designed so that vo = kvs at no load (RL = ∞) and vo = αvs at full load (RL= Ro). Note that by definition α1.

a) Show that

and

---

b) Specify the numerical values of R1 and R2 if k = 0.85, α = 0.80, and Ro = 34 kΩ.

---

c) If vs = 60 V, specify the maximum power that will be dissipated in R1 and R2.

---

d) Assume the load resistor is accidentally short circuited. How much power is dissipated in R1and R2?
