Homework Help: Electrical Circuit and Current

  1. Feb 23, 2007 #1
    1. The problem statement, all variables and given/known data

    In the circuit shown in the figure, the rate at which R1 is dissipating electrical energy is 20.0 W.

    I just have questions about the circuit's setup. The resistors are arranged in a parallel circuit?

    As for the purple arrows, is 2.00 A I_1 and 3.50 A the total current in the circuit?

    2. Relevant equations

    See below.

    3. The attempt at a solution

    This is just a preliminary question. I shall post my workings at a later time if I am baffled by the questions associated with the figure.

    Thanks.

    Sounds good to me so far.

    Yes, the resistors are in parallel.

    That's how I would interpret them.
