Homework Help: Basic resistor circuit

  1. Mar 22, 2010 #1
    1. The problem statement, all variables and given/known data
    In the pictured, the battery puts out 12 volts, R1 is 9 ohms, R2 is 6 ohms, and R3 is 5 ohms.

    What current flows through resistor R1?

    Please use only SI (metric) system units in your answer!


    2. Relevant equations

    R=V/I ???

    3. The attempt at a solution

    I am completely lost...
