Simple Circuit Question

  1. Apr 14, 2007 #1

    I have a simple circuit question. I was just wondering why I(o3) = 0? (see link)

    - Is it because current always follows the path of least resistance?
    - So the current flows through the empty branch and not beyond that?
    - Are the two remaining 4 kilo(ohm) useless?

    Basically yes, you shorted out the two 4k Ohm resistors, no current is going to flow down that branch.
