Node Analysis Question

  1. Sep 23, 2008 #1
    1. The problem statement, all variables and given/known data

    This is first time i came across this problem. But lets say u have two loop circuit. in the middle u have a a resistor going down and a it shows lets say 4A current after the resistor. After i make my ground point lets say at bottom of this circuit. Would the equation be just +/- 6A based on which direction the current is flowing ?

    Your question isn't very clear. At a node, the sum of the currents flowing into the node must equal the sum of the currents flowing out of the node.

    As for the 4A flowing "after" the resistor, it is actually 4A flowing through the resistor (between the two nodes that make up the central branch the current is 4A at any point on the branch).
