    Circut help!!!

    1. The problem statement, all variables and given/known data

    In the circuit shown below, the batteries have negligible internal resistance.

    (a) Find the magnitude of the current in each resistor.

    I3 = ?? A

    I4 = ?? A

    I6 = ?? A

    2. Relevant equations


    i dont know where to begin because there are two batteries??
    any help would be great

    Re: Circut help!!!

    Hint: 2 batteries, but one voltage. Can you find a simpler equivalent circuit (from the resistors' point of view) based on this observation?
