D *1.9 Two resistors, with nominal values of 470 Ω and 1 kΩ, are used in a voltage divider with a +3-V supply to create a nominal +1-V output. Assuming the resistor values to be exact, what is the actual output voltage produced? Which resistor must be shunted (paralleled) by what third resistor to create a voltage-divider output of 1.00 V? If an output resistance of exactly 333 Ω is also required, what do you suggest?
0.96 V; shunt the 1-kresistor with 15.67 k; add series 20
