Using no more than four 1-k \(\Omega\) resistors, all but one of the following equivalent resistors can be constructed: 1 \(\mathrm{k} \Omega, 2 \mathrm{k} \Omega, 500 \Omega, 1.5 \mathrm{k} \Omega, 2.5 \mathrm{k} \Omega, 3 \mathrm{k} \Omega, 333 \Omega, 250 \Omega, 1.33 \mathrm{k} \Omega\), \(2.33 \mathrm{k} \Omega\), and \(4 \mathrm{k} \Omega\). Which one cannot be constructed with only four \(1-\mathrm{k} \Omega\) resistors? Show how you would construct the others.
