A voltage divider like that in Fig. 3.13 is to be PROBLEM designed so that v0 = kvs at no load (RL = oo) and v0 = avs at full load (RL = Ra). Note that by definition a < k < 1. a) Show that and _ k - a R\ - ; K ak R, k a a{\ - k) K b) Specify the numerical values of R[ and R2 if k = 0.85, a = 0.80, and R0 = 34 kO. c) If vs = 60 V, specify the maximum power that will be dissipated in R\ and R2. d) Assume the load resistor is accidentally short circuited. How much power is dissipated in Rx and /?2?
