    That level of precision in a resistor would literally be thrown off if you breathed on it. If you actually needed that, then you need to build an extremely controlled environment around it. Even then, the heat from the electricity itself would throw it off. Maybe in a liquid nitrogen bath?

      A big aspect of good design is being able to solve an issue as succinctly as possible, with as wide an operating range as possible. Lower tolerance requirements = better.

      If you need that level of precision, you might want to reconsider your career in circuit design.

      First, assume a spherical resistor in a vacuum, that can also dissipate heat with 100% efficiency.

      Now that we’re in physics land, anything is possible.
