I'm sorry but this is the wrong answer. Remember that each branch has the entire voltage across it.

Applying Ohm's law to the top branch:


=6/4 A


The lower branch has a combined resistance of 4Ω because the two resistirs are in series.

Applying Ohm's law to the bottom branch: I=V/R

=6/(2+2) A
