Zo=50 ohms Vrms =1V I(total) = Vrms/Zo = 1/50 I(total) will flow through the first resistor and split through the next 2, I(half). Voltage across the first resistor=16/I(total) Votage across the next 2 = 16 / I(half). So 1/50 = .02A Vr1= .02A*16=.32 Vr2= .01A*16=.16 Vr3= .01A*16=.16 =.32+.16 = .48V Since the circuit is symetrical this works out in every direction. Rod
