Homework Statement



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

Homework Equations



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

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...
