Current direction after changing inductor to short circuit

  1. Jan 10, 2017 #1
    1. The problem statement, all variables and given/known data
    In the figure in the picture uploaded assume that the switch has been closed for a long time such that the inductor acts like a short circuit. Through which resistors does the current pass through and why??

    2. Relevant equations
    A short circuit is basically a wire or a zero resistance, and as we know current passes through the path with least resistance.

    3. The attempt at a solution
    I know what the solution but I don't understand why, it says the current won't pass through the 3Ω resistor... Is it because no potential difference is across it meaning that the current would be zero??
    Thank you
