    What is the current through the ammeter in the figure?

    I cant for the life of me figure out how to do this question ? could someone please help with this ??
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    I dont think the resistance of the ammeter is factored, take it as negligible.

    I was, why don't you?
    Now what is the potential difference across it?
    You need to find the current through each resistor to
    deduce what must flow through the ammeter.

    For the purpose of this question the resistance of the ammeter is considered negligible as has been instructed by teacher
