      Based on some rough calculations… no. A precision of 0.0000000000001 ohms is 1000x less than the resistance of 1um of copper with a diameter of 1cm (A piece of wire 10,000x wider than it is long). I’m sure a few molecules of air between your contact points would cause more noise in the measurement.

      I thought it had to do with physicists working off theoretical calculations finding precise values for the circuit and not realizing that components come in discrete values.

        Yeah, but they could just calculate the right mix of parallel and series discrete resistors to get there.

        It’s gonna make a long BOM though.

          Lol, I was actually going to add that but decided it would be too pedantic if I said it myself.
