Internal resistance of a source

  1. Apr 5, 2008 #1
    1. The problem statement, all variables and given/known data

    A rule of thumb used to determine the internal resistance of a source is that it is the open-circuit voltage divided by the short-circuit current. Is this correct? Why or why not?

    thx for any help
