    Hey Guys I need to find the voltages in every node and the curretns, when every resistance is 2ohms. I put the equations, but dont know how to find out.

    Any help would be appreciated.

    You can use Ohm's Law and Kirchoff's Laws; we've only got a crystal ball to work with ;).

    Mod edit: moved to current thread.

    First, decide which method you are going to use to solve for the unknowns. Choose to use the mesh equations or the node equations, not both.

    Next, substitute the known values of currents/voltages and resistors into the equations to simplify. There are only two unknown voltages or currents so you should be able to get the information down to two equations and 2 unknowns.

    For the most part you are doing okay, but ask yourself if it make sense that your mesh equation for I2 has a term in it that doesn't include I2?
