    Omg thank you I thought resistors were in parallel this makes sense

    when u redrew it as a circuit how would us know if it was in parallel

    The resistors look like they are in parallel though without making the circuit diagram, thats how i was getting the wrong answer

    why did not use p=I2R

      If you have enough info, you can use that too!
