Homework Statement:
 What is the Current Through A Resistor in Parallel?
Relevant Equations:

I = V/R
Resistors in Parallel => 1/R = 1/R1 + 1/R2
Resistors in Series => R = R1 + R2
Here is the actual question.
And here is my attempt at a solution
In Summary I did the following
 Found the Equivalence Resistance to Be 5.9 ohms and the Current throughout the entire resistor to be 1.53 Amperes
 Worked backwards from my resistor simplifications. When the resistors were in series I solved for V because they should have the same Current. When they were in parallel I solved for Current because they had the same voltage.
 Eventually I worked my way back to the parallel resistors of 4.3 and 12 ohms and got .166 Amperes of current running through the 12 ohms resistor.
 This answer, however, was wrong. I found this method from this video on Khan Academy https://www.khanacademy.org/science...examplefindingcurrentvoltageinacircuit.
