    Pic on circuit attached
    need to work out:

    a. The current flowing in each circuit branch and its direction
    b. The power dissipated in the 10ohm resister

    This is probably simple to most of yous but i dont have a clue what to do :S

    Welcome to PF!

    Hi TooJazzy! Welcome to PF! :wink:

    Start by calling the three currents I1 I2 and I3.

    Then write out the three Kirchhoff's equations, for two loops and one node …

    what do you get? :smile:
