Calculating Amperes for converging electrical pathway

  1. Mar 18, 2012 #1
    1. The problem statement, all variables and given/known data

    Question shows one arrow with 10 amperes heading in one direction, which splits into three different pathways. having two labels of 4 and 6 amperes.

    2. Relevant equations

    To be honest I don't know what equations I would use; the courseware really wasn't much help.

    3. The attempt at a solution

    The only answer I could guess was zero.

    Were direction arrows given for the 4 and 6 ampere currents?

    No angles were given; they just point away from the first arrow

    So what is your question?

    Some form of a diagram would be a big help.

    Angles? The arrows should parallel the wires that they are associated with. They will show the direction that the current flows in the given wire. If you have those directions, then investigate Kirchhoff's current law (KCL) in your notes.

    Attached is the diagram for the question, I need to find the value of "I". Thanks

    Did you investigate KCL?
