Homework Help: Engineering Science

  1. Jun 6, 2007 #1
    1. The problem statement, all variables and given/known data

    Is it possible to measure a physical parameter without removing energy from the system under test? If not, describe why not.

    2. Relevant equations

    3. The attempt at a solution

    No it is not possible because when testing the system be it voltage, temperature, speed etc. the testing equipment cannot run at the same ratio that the energy is.
    Ive no idea really any help would be much appreciated or any links showing me why it is not possible
