Define a steady state current ?

  1. Mar 6, 2015 #1
    For a steady state current, is ##\frac{dI}{dt}=0## or is ##\frac{\partial I}{\partial t} = 0##?

    Steady state anything means partial derivative with respect to time is 0. Often the quantity of interest is only a function of time, so you can change it to a normal derivative.

    I think you'd need to specify the situation that you would be describing in order to make the choice of which to use.
