Answer

First, you can ignore the 2 ohm resistor since all the current needs to go through there. Then, apply the current division formula to the other two resistors. Take the 3 ohm resistor and divide by the sum of the 3 and 6 ohm resistors, and multiply this quantity by the 12 amps from the source. The answer is 4 amps.
