Combination Circuit HW problem

  1. Apr 19, 2014 #1
    1. The problem statement, all variables and given/known data

    http://imgur.com/h5VXibe

    Have to solve V, I, R and Power for all resistors and the circuit total. Known data is shown in table. The rest needs to be solved for

    2. Relevant equations

    Ohm's Law and Series Equation: 1/Er=1/R1+1/R2... and Tr=R1+R2...


    3. The attempt at a solution

    Added up parallel circuit and found Er to be .4 ohms. Not sure where to go next.

    Begin by finding the equivalent resistance for the whole circuit by applying Ohms law to the circuit.

    I'm not sure how to approach that.

    You know Ohms law right? What's the voltage applied to the circuit and what's the current moving through it?

    Please show your work. The combination of R2, R3, R4 is not 0.4 Ohms...
